Question

A round baby pool holds 48.2 cubic feet of water. If the pool has a radius of 3.2 feet, what is the height of the pool in feet? Round your answer to the nearest tenth.

Answer 1

The formula for the volume of a cylinder is
  V = π×r²×h

Substitute your given numbers and solve for h.
  48.2 ft³ = π×(3.2 ft)²×h
  h = (48.2 ft³)/(π×(3.2 ft)²)
  h ≈ 1.5 ft

The height of the pool is about 1.5 feet.
