Question

The volume of a cylinder is 980π in3. The radius of the cylinder is 7 in. What is its height? 10 in. 20 in. 140 in. 70 in. Description

Answer 1

The answer is 20 in

Answer 2

First, you have to set up the equation. In this case, we would plug in what we know into the volume of a cylinder equation (V=$\pi$$r^{2}$h).

We get:
980$\pi$= $\pi$($7^{2}$)(h)

Then, after solving for what we know:

980$\pi$= 49$\pi$(h)

Divide both sides by 49$\pi$. The $\pi$ cancels out and you're left with:

20= h

So the height of the cylinder is 20.
