A cylindrical tank has a radius of 1 foot and a height of 10 feet and is completely empty.

Air is pumped in at the rate of [tex]8\pi[/tex] cubic feet per minute.

Air is leaking out at the rate of [tex]3\pi[/tex] cubic feet per minute.

When will the tank be half full?

How do you fill a tank

**half full**of air?
