Step-by-step explanation:

The area of the circle is approximately 30,000 [tex]m^{2}[/tex]

The circumference of the circle is given as 600m.

And we know that circumference = [tex]2\pi r[/tex] where r is the radius of the circle.

Therefore,

[tex]2\pi r = 600[/tex]

[tex]r = \frac{600}{2\pi }[/tex]

[tex]r = \frac{300}{\pi }[/tex]

Now, we know that area of the circle = [tex]\pi r^{2}[/tex]

Putting the value of r in this, we get

area = [tex]\pi (\frac{300}{\pi } )^{2}[/tex]

area = [tex]\pi.\frac{300}{\pi } .\frac{300}{\pi }[/tex]

Therefore, area of the circle = 28,647.889 [tex]m^{2}[/tex]

Therefore, the correct answer is 30,000 [tex]m^{2}[/tex]

Answer:

Step-by-step explanation:

well, it all starts with a check, what calculations in the answer options are even correct.

A. is correct. 0.66/3 = 0.22

B. is incorrect

C. is incorrect

D. is correct. 0.78/3 = 0.26

so is it A or B ?

one group of 2 tens and 6 ones : how much is that ?

2×10 + 6×1 = 20 + 6 = 26

3 groups of 26 means

3×26 = 78

so, the combination of the 3 groups would either show that

3×26 = 78

or

78/3 = 26

and that is the same as showing

0.78/3 = 0.26

because

0.78 = 78/100

0.26 = 26/100

therefore

78/100 / 3 = 26/100

78/100 = 3×26/100 = 78/100

correct.

The correct answer is a) Lunar eclipses can be viewed from more places on Earth than solar eclipses. This is because lunar eclipses are visible from any location on the night side of Earth, whereas solar eclipses are only visible from certain locations along the Moon's shadow path.

The correct answer is c) the changes of the seasons on Earth. The amount of sunlight that strikes different parts of Earth due to Earth's tilt on its axis affects the seasons on Earth because it determines the length of the days and the angle at which sunlight hits the Earth, which in turn affect the temperature and weather patterns in different regions.

The correct answer is b) Kinesha is incorrect because a solar eclipse occurs when the Moon is directly between the Sun and Earth. A solar eclipse occurs when the Moon is directly between the Sun and Earth, and the Moon's shadow is cast on Earth. In this configuration, Earth is not located between the Sun and the Moon.

The correct answer is b) new moon. During the new moon phase, the Moon is positioned between the Earth and the Sun, and its illuminated side is facing away from Earth. As a result, the Moon appears to be unlit by sunlight from Earth's perspective.

The correct answer is c) two different sized foam balls to represent Earth and the Moon and a light source to represent the Sun. This model would allow an observer to see the relative positions of Earth, the Moon, and the Sun, and how they change as the Moon goes through its phases.

The correct answer is d) in the order of the Moon, Earth, and the Sun in a straight line. During a total eclipse of the Sun, the Moon is positioned directly between the Sun and Earth, and its shadow is cast on Earth. In this configuration, the Moon, Earth, and the Sun are aligned in a straight line, with the Moon in the middle.

The correct answer is b) Y. If the state of Georgia is experiencing spring, then Earth must be in a position where the northern hemisphere is tilted towards the Sun. In the diagram, this is represented by position Y, where the northern hemisphere is pointing towards the Sun and the southern hemisphere is pointing away from the Sun.

The correct answer is c) Model 1 can be used to demonstrate a full moon, and Model 2 can be used to demonstrate a waning crescent moon. Model 1 shows the Moon with its illuminated side facing towards the observer, which is what happens during a full moon. Model 2 shows the Moon with a small part of its illuminated side visible, which is what happens during a waning crescent moon.

The correct answer is a) The equator receives more direct sunlight through all the seasons of the year and this produces a warmer climate than South Africa. The equator is located at 0 degrees latitude, where the Sun's rays are directly overhead throughout the year. This means that the equator receives more direct sunlight than other latitudes, which produces a warmer climate. In contrast, South Africa is located at about 30 degrees latitude, where the Sun's rays are less direct, which produces a cooler climate.

An observer standing on the Moon during a solar eclipse would see the Earth fully covered by the Moon's shadow. This is because the Moon's shadow is cast on Earth during a solar eclipse, and from the Moon's perspective, the Earth would be fully within the shadow.

In order to solve this problem, we need a few formulas to help us get to the answer:

The first formula we need is the Slope Formula:
[tex]\displaystyle m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

where (x₁, y₁) and (x₂, y₂) are two different points.

The second formula we need is Point-Slope Form:
[tex]\displaystyle y - y_0 = m(x - x_0)[/tex]

where (x₀, y₀) is a given point on the line and m is the slope.

Now, we can organize and define what the problem has given us:

We are first given information that a line passes through the points (6, 2) and (2, 4).

We are also given that the parallel line passes through (-1, 6).

Let's first find the slope of the line that passes through two points:

[tex]\displaystyle\begin{aligned}m & = \frac{4 - 2}{2 - 6} \\& = \frac{2}{-4} \\& = \boxed{ - \frac{1}{2} } \\\end{aligned}[/tex]

∴ we know that the slope is equal to negative one-half.

Let's substitute in our slope into Point-Slope Form since parallel lines have the same slope:

[tex]\displaystyle y - y_0 = m(x - x_0) \Rightarrow y - y_0 = - \frac{1}{2} (x - x_0)[/tex]

Recall that we were given the initial point (-1, 6). Let's also substitute this into Point-Slope Form:

[tex]\displaystyle \begin{aligned}y - y_0 = m(x - x_0) & \Rightarrow y - y_0 = - \frac{1}{2} (x - x_0) \\& \Rightarrow y - 6 = - \frac{1}{2} (x - -1) \\& \Rightarrow \boxed{ y - 6 = -\frac{1}{2}(x + 1) } \\\end{aligned}[/tex]

∴ we have found that the point-slope form of the equation of a line that passes through the point (-1, 6) and is parallel to the line that passes through the points (6, 2) and (2, 4) is equal to:
[tex]\displaystyle \boxed{ y - 6 = -\frac{1}{2}(x + 1) }[/tex]

Hope this helps!

Answer:

If x and y vary directly and y is 6 when x is 8, y is 9 when x is 12.

Step-by-step explanation:

In the given problem, it is known that when x is 8, y is 6, so the constant of proportionality in this case is k = y/x = 6/8 = 3/4. This means that the relationship between x and y can be written as y = (3/4)x.

To find the value of y when x is 12, we can plug this value into the equation to get y = (3/4) * 12 = 9. Therefore, if x and y vary directly and y is 6 when x is 8, y is 9 when x is 12.

Answer:

An eclipse happens when a celestial object moves into the shadow made by another celestial object. In the case of a solar eclipse, the Moon moves into the shadow of the Earth, and in the case of a lunar eclipse, Earth moves into the shadow of the Moon.

The most likely reason for the Sun always shining in the summer in Barrow, Alaska is that Earth's axis is tilted, so sometimes parts of Earth face the Sun for the entire daily rotation.

When Earth is in Position C in the diagram, it is spring in the Northern Hemisphere because the Northern Hemisphere is tilting toward the Sun and receiving more direct sunlight than Position B.

The city that will most likely experience the mildest winters is Tallahassee, Florida because it is closest to the equator and receives the most direct sunlight.

When Earth, the Sun, and the Moon line up in a straight line, a lunar or solar eclipse can happen.

The point that indicates the location of the Moon that is the best for viewing a lunar eclipse from Earth is P.

A solar eclipse can only happen during a new moon because, during a new moon, the Moon is between the Sun and Earth. This allows the Moon to block the sunlight and create an eclipse.

Answer:

During a total lunar eclipse, Earth blocks sunlight from reaching the Moon. Earth casts a shadow onto the Moon. The Moon can look reddish orange.An eclipse occurs when one heavenly body such as a moon or planet moves into the shadow of another heavenly body. Let’s learn about the two types of eclipses on Earth.What Is a Lunar Eclipse?The Moon moves in an orbit around Earth. At the same time, Earth orbits the Sun. Sometimes Earth moves between the Sun and the Moon. When this happens, Earth blocks the sunlight that normally is reflected by the Moon. (This sunlight is what causes the Moon to shine.) Instead of light hitting the Moon's surface, Earth's shadow falls on the Moon. This is an eclipse of the Moon, or a lunar eclipse. A lunar eclipse can occur only when the Moon is full.A lunar eclipse can be seen from Earth at night. There are two types of lunar eclipses: Although the Moon is in Earth's shadow, some sunlight reaches the Moon. The sunlight passes through Earth's atmosphere, which filters out most of the blue light. This makes the Moon appear red to people on Earth.Earth's shadow passes in front of the Moon until it turns red or orange.A partial lunar eclipse happens when part of the Moon enters Earth's shadow. In a partial eclipse, Earth's shadow appears very dark on the side of the Moon facing Earth. What people see from Earth during a partial lunar eclipse depends on how the Sun, Earth and Moon align.A lunar eclipse usually lasts for a few hours. At least two partial lunar eclipses happen every year, but total lunar eclipses are rare. It is safe to look at a lunar eclipse.
