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.
