Question

An empty swimming pool needs to be filled to the top. The pool is shaped like a cylinder with a diameter of 8 m and a depth of 1.9 m. Suppose water is pumped into the pool at a rate of 16 m3 per hour. How many hours will it take to fill the empty pool?

Answer 1

Explanation:

volume of the pool=3.14×4²×1.9=95.456 m³

time required=96.456÷16=5.966 hrs≈10 hrs

Answer 2

5.97 hours to the nearest hundredth.

Explanation:

The volume of water in the pool = π r^2 h

= π * 4^2 * 1.9 m^3

Time to fill the pool = (π * 4^2 * 1.9 ) / 16

= 5.97 hours.
