Question

A swimming pool has to be drained for maintenance. The pool is shaped like a cylinder with a diameter of 10m and a depth of 1.4m. Suppose water is pumped out of the pool at a rate of 18 m3 per hour. If the pool starts completely full, how many hours will it take to empty the pool?

Answer 1

Answer:

6.1 hrs

Step-by-step explanation:

Volume of the cylinder = pi * (10/2)^2 * 1.4 m^3 = 109.956 m^3

So, time required = 109.953/18 hrs = 6.108 hrs ≈ 6.1 hrs
