so the formula to find the area of a circle is A = pie x r or (radius)^2 so the radius is just squared.
so the radius of the circle is 3 so you would square that.
pie is 3.14(rounded)
A = 3.14(pie) x 3^2
A = 3.14 x 9
A = 28.26

Answers

Answer:

the surface area is 3140 square feet

Step-by-step explanation:

The computation of the surface area is given below:

Given that

Diameter = 20 feet

radius =  20 ÷ 2 = 10 feet

Surface area = [tex]2\pi r^2 + 2\pi rh[/tex]

= 2 × 3.14 × (10)^2 + 2 × 3.14 × 10 × 40

= 6.28  × 100  + 6.28  × 400

= 628 + 25.12  × 100

= 628+ 2512

= 3140 square feet

hence, the surface area is 3140 square feet

ABC is a right triangle. If AC=4 and BC=10, find AB. Leave your answer is the simplest radical form. ​

Answers

Answer:

√116 or √84

Step-by-step explanation:

ABC is a right triangle

AC=4, BC=10, AB = ?

Here we have two options:

1. AB is hypotenuse, then:

AB = [tex]\sqrt{AC^2 + BC^2} = \sqrt{4^2 + 10^2} = \sqrt{16 + 100} =\sqrt{116}[/tex]

2. BC is hypotenuse and AB is the second leg, then:

AB = [tex]\sqrt{BC^2 - AC^2} = \sqrt{10^2 - 4^2} = \sqrt{100 - 16} = \sqrt{84}[/tex]

A student said that x = 4 was not a solution to the question 3(x -6) = -8
Here is their work:
3(x -6) = -8
3 (4 -6) = -8
12 -6 = -8
6≠ -8
so x = 4 is not a solution

Did the student substitute x=4 correctly? How do you know?

Did the student simplify with Order of Operations correctly? How do you know?

If you try the problem, what do you get when you substitute x=4 into the equation?

Answers

Answer:

Step-by-step explanation:

3 (4 -6) = -8 is correct.  The next step is to combine 4 and -6, obtaining

3(-2)

and this 3(-2) should equal -6, which is not the same as -8.

3(4 - 6) = 12 - 18, which differs from the student's solution.  This is the reason for the wrong answer.

Hummingbirds have unusually large hearts for their body size. If a person's heart were as

big as a hummingbird's, his or her heart would weigh as much as a large dog.

Information you will need:

An average hummingbird weighs 0.3524 ounces and has a heart that weighs 0.00875

ounces.

1 pound = 16 ounces

The average weight of a large dog is usually more than 80 pounds.

Leo weighs 192 pounds.

a.) How much would Leo's heart weigh if it were the same ratio as a hummingbird's?

Show your work on your paper.

b.) is the original claim true or false? Justify your reasoning here along with your answer.

Answers

Answer: 4.8lbs, This claim is false

Step-by-step explanation:

Leo weighs 192 pounds. Then Leo's heart weight will be 76.258 ounces. So, its claim is false.

What are ratio and proportion?

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

Hummingbirds have abnormally huge hearts for their body size. In the event that an individual's heart was essentially as large as a hummingbird's, their heart would weigh as much as an enormous canine's. A typical hummingbird weighs 0.3524 ounces and has a heart that weighs 0.00875 ounces.

The ratio of heart to weight is given as,

Ratio = 0.00875 / 0.3524

Ratio = 0.024829

The average weight of a large dog is usually more than 80 pounds. Leo weighs 192 pounds. Then Leo's heart weight is calculated as,

⇒ 0.024829 x 192 x 16

⇒ 76.28 ounces

Their heart weight of Leo is less than the weight of the dog. So, its claim is false.

The domain of a quadratic is all real numbers.
a) True
b) False

Answers

A) True

The domain of a quadratic function in standard form is always all real numbers, meaning you can substitute any real number for x. The range of a function is the set of all real values of y that you can get by plugging real numbers into x.

Answer:

Step-by-step explanation:

I'd be very hesitant to say true.

If the quadratic is in the form of y = x^2 then the statement is correct. The entire family all have a domain of all the real numbers.

However if the quadratic is of the form x=y^2 then the starting point of this quadratic is (0,0). All of these quadratics have a different starting point. \\

Since you have not specified the kind of quadratic, the answer is not always true.

1) x-axis which is the horizontal axis.

2) y-axis which is the vertical axis.

The intersection of both the axes is known as the origin whose coordiantes are (0,0), i.e. at this point value of x =0 and value of y =0.

The formula for the gravitational potential energy of an object is U = mgh, where U represents the potential energy, m represents the mass of the object, g represents the acceleration due to gravity, and h represents the object’s height above the ground. Solve this formula for h.

Answers

U=mgh

U/m=gh

U/mg=h

therefore:

h=U/mg

The solution for h is h = U / (mg),

where U represents the potential energy, m represents the mass of the object, and g represents the acceleration due to gravity.

Here, we have,

To solve the formula U = mgh for h (the height above the ground),

we need to isolate h on one side of the equation.

Here are the steps:

Start by dividing both sides of the equation by mg:

U / (mg) = (mgh) / (mg)

This simplifies to:

U / (mg) = h

Now we have isolated h on one side of the equation.

Therefore, the formula for h is:

h = U / (mg)

So, the solution for h is h = U / (mg),

where U represents the potential energy, m represents the mass of the object, and g represents the acceleration due to gravity.

In rhombus CATS, CA= 6x-30. AT= 2x+30 find the perimeter? I need help ASAP PLEASE

Answers

Length of CA = 6x - 30

Length of AT = 2x + 30

We know that all sides of a rhombus are congruent.

Which means :

[tex] = 6x - 30 = 2x + 30[/tex]

[tex] = 6x - 30 - 2x = 30[/tex]

[tex] = 4x - 30 = 30[/tex]

[tex] = 4x = 30 + 30[/tex]

[tex] = 4x = 60[/tex]

[tex] = x = \frac{60}{4} [/tex]

[tex] = x = 15[/tex]

Thus, the value of x = 15

Then :

Measure of CA :

[tex] = 6x - 30[/tex]

[tex] = 6 \times 15 - 30[/tex]

[tex] = 90 - 30[/tex]

[tex] = 60[/tex]

Thus, measure of CA = 60

Measure of AT :

[tex] = 2x + 30[/tex]

[tex] = 2 \times 15 + 30[/tex]

[tex] = 30 + 30[/tex]

[tex] = 60[/tex]

Thus, measure of AT = 60

Perimefer of rhombus CAT :

[tex] = 4 \times side[/tex]

[tex] = 4 \times 60[/tex]

[tex] = \color{plum}240[/tex]

Therefore, the perimeter of rhombus CAT = 240
