Question

Stella has a cylindrical pool. She needs 20 cubic meters of water to fill the pool to the top. The pool has a diameter of 3 m. Using π ≈ 3.14, which is the approximate height of the pool?

Answer 1

It is approximately 2.831 m or 3 m height:

V=πr²h

h=V/(πr²)

h=20m³/(3.14(3/2)²)

h=2.831m
