Answer:

30 inches

Step-by-step explanation:

The circumference of a circle can be found by using 2 $\pi$ r, or $\pi$ * d.

Since we are given the circumference of the circle, 30 $\pi$ , you can find the diameter by solving for the diameter (after substituting in the circumference) in the formula for circumference.

$30\pi =\pi *d$

To cancel out $\pi$ you can divide both sides of the equation by pi. Now you have:

30 = d

Therefore the diameter of the circle is 30 inches.

a cylinder has a radius of 5 inches and the total volume of 175 pi cubic inches. what is the height of cylinder?

DENIUS [597]

Answer:

<h2>The height of cylinder = 7 inches</h2>

Step-by-step explanation:

The formula of a volume of a cylinder:

$V=\pi r^2H$

r - radius

H - height

We have

r = 5 in

V = 175π in³

Substitute:

$175\pi=\pi(5^2)(H)\\\\175\pi=25\pi H\qquad\text{divide both sides by }\ 25\pi\\\\\dfrac{175\pi}{25\pi}=\dfrac{25\pi H}{25\pi}\\\\7=H\to H=7\ in$
