A swimming pool has to be drained for maintenance. The pool is shaped like a cylinder with a diameter of 6 m and a depth of 1.3 m. Suppose water is pumpedout of the pool at a rate of 12 m' per hour. If the pool starts completely full, how many hourswill it take to empty the pool?

In this case, we going to need the formula for the volume of a cylinder:


\pi r^2h

being r the radius and h the depth


\pi\cdot3^2\cdot1.3=36.7566

The ratio of pumped is 12

so we divide the volume of the pool by the ratio to get the time


(36.7566)/(12)=3.0630

Answer: 3.063 hours
