The diameter of a circle is 6 cm. What is the area of the circle to the nearest square meter?

Answers

Answer 1

Answer:

0.002827 m^2

Step-by-step explanation:

A = pi * r^2

d = 2r

r = 3 cm = 0.03 m

A = pi * (0.03) ^ 2

A = 0.002827 m^2

Answer 2

The area of the circle is - 0.028 [tex]m^{2}[/tex]

The diameter (D) of a circle - 6cm

A diameter is a line that passes through the center of a circle and meets the circumference at the opposite site.The radius of a circle is the distance between the center point to any other point on the circle.The diameter is equal to half of the radius(r).

                          D=[tex]\frac{r}{2}[/tex]

The radius of a circle is = [tex]\frac{6}{2}[/tex] cm

                                      = 3 cm  = 0.03 meter

Now,  

       The formula of the area of a circle  = π[tex]r^{2}[/tex]

                    (the value of π = [tex]\frac{22}{7}[/tex] )

        Area of a circle = [tex]\frac{22}{7}[/tex] * [tex](0.03)^{2}[/tex]   [tex]m^{2}[/tex]

                                  =[tex]\frac{22}{7}[/tex] * 0.0009 [tex]m^{2}[/tex]

                                  = 0.028 [tex]m^{2}[/tex]

∴ The area of the circle is - 0.028 [tex]m^{2}[/tex]

Which table does not represent a relationship that is directly proportional? Btw i clicked a by accident

Answers

Answer:

The selected option

Step-by-step explanation:

Coincidentally, you answered correctly.

From the values of 3 and five, we can assume that the function of the table is Y=x+2.

But if we move to the next value pairs, that function is false.

10=6+2 that isn't correct.

If you apply this to all the pairs in the table you will find that there is not a function that represents the values given. Therefore, the first option is correct.

Use point slope form to write the equation of a line slope intercept form that passes through the points 0,-5 and -3,4

Answers

Answer:

y + 5 = -3(x - 0)

Step-by-step explanation:

First, you find the slope. To do that, you subtract the second y point (in this case 4) by the first y point (in this case -5), and you get 9. Then, you subtract the second x point (in this case -3) by the first x point (in this case 0), and you get -3. Y is over X, so you get 9/-3 or 9 over -3, which can simplify to -3.

Next, you use the point slope formula: y - y1 = m(x - x1). Add in the y1, m, and x1, then solve if it asks you to put it in slope intercept form. So, for this case, it would be y + 5 = -3(x - 0)

compute the distance between (9,-5,4) and (-10,3,4)

Answers

Answer:

~20.6155

Step-by-step explanation:

To compute distance between two points, we can get the vector from one to the other by subtracting them and then computing the length of the vector.

The length of a vector V is:

[tex]|V| = \sqrt{\sum_{i=1}^n v_i^2}\\[/tex]

The vector is:

(9, -5. 4) - (-10, 3, 4) = (9 + 10, -5 - 3, 4 - 4) = (19, -8, 0)

So the length is:

[tex]\sqrt{19^2 + (-8)^2} = \sqrt{361 + 64} = \sqrt{425} = \sqrt{5\cdot 5\cdot 17} = 5\sqrt{17} \approx 20.6155281281[/tex]

The equation for the number 40 is 5 times as many as 8 is; 40=5×8

What does it mean to solve an equation?

An equation represents equality of two or more mathematical expression.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

Solutions to an equation are those values of the variables involved in that equation for which the equation is true.

We are given that the number 40 is 5 times as many as 8

Answers

Answer:

A

Step-by-step explanation:

The secant- secant angle is half the difference of the intercepted arcs, then

[tex]\frac{1}{2}[/tex] (20x - 7x - 11) = 40 ( multiply both sides by 2 to clear the fraction )

13x - 11 = 80 ( add 11 to both sides )

13x = 91 ( divide both sides by 13 )

x = 7

Then

arc HD = 20x = 20 × 7 = 140° → A
