Answer:

radius = 16 inches

C = 32pi or approximately 100.48 inches

Step-by-step explanation:

We know the diameter is twice the radius

d = 2r

32 = 2r

Divide each side by 2

32/2 =2r/2

16 =r

The radius is 16 inches

The circumference is equal to

C = pi * diameter

C = pi *32

C = 32 pi inches

Letting pi  be approximated by 3.14

The circumference is approximately 100.48 in

The radius is 16 inches.

This is because the radius is half the diameter and since we know that the diameter is 32 inches you just have to divide it by 2.

The circumference is 32 pi

This is because the circumference is 2 times pi times radius. This means that is is diameter times pi. This is because we know that that 2 times the radius is equal to the diameter.

Answer:

#15) B. 30 mn^5

#17) B. 1/2

Step-by-step explanation:

<h2>#15:</h2>

The area of a trapezoid is given in the formula: 1/2(a + b) * h, where a is the length of the top of the trapezoid, b is the length of the bottom of the trapezoid, and h is the height of the trapezoid.

All of these measurements are given so all that you need to do is to substitute these values into the formula.

Substitute 3 for a, 9 for b, and 5 for h.

  • 1/2(3 + 9) * 5

Solve inside the parentheses first. Add 3 and 9.

  • 1/2(12) * 5

Multiply 12 and 1/2 together.

  • 6 * 5

Multiply 6 and 5.

  • 30

We need to figure out if the area is to the 5th or 6th power. When we added 3 and 9 together, we combined like terms so the exponent stayed to the 3rd power.

After multiplying this ^3 by the 5mn^2, the exponent becomes to the 5th power because you add exponents when multiplying.

Therefore the final answer is B. 30 mn^5.

<h2>#17:</h2>

When going down from 32 to 8 to 2, you can see that each number is being divided by 4.

32 / 4 = 8...

8 / 4 = 2...

So to find the next number in this sequence you would divide 2 by 4.

  • 2 / 4 = 1/2

The answer is B. 1/2.
