A swimming pool has to be drained for maintenance. The pool is shaped like a cylinder with a diameter of 8m and a depth of 1.6m . If the water is pumped out of the pool at the rate of 11m^3 per hour, how many hours does it take to empty the pool? Use the value 3.14 for Pi , and round your answer to the nearest hour.
