Answer:

The height is 15.992 in

Explanation:

1. The equation for a cylinder is
$V=\pi r^2h$ . In this case, the equation looks like
$615.44=\pi (3.5)^2h$

2. Isolate h by dividing both sides of the equation by
$\pi (3.5)^2$

3. This leaves us with
$(615.44)/(\pi (3.5)^2)=h$

4. Solve for the left side, which leaves us with h = 15.992 (rounded to the nearest thousandth)
