Question

Miriam is setting up a fishing game in a kiddie pool for her niece's birthday party. The pool has a circular base with a diameter of 4 feet and a height of 0.75 feet. She wants to fill the pool halfway so there is plenty of space left for the plastic fish. Approximately how many cubic feet of water does she need? 9.4 1.5 2.4 4.7

Answer 1

4.7 feet³ of water

Explanation:

Diameter of 4 feet

Radius = 2 feet

Height = 0.75 feet

Formula for Volume = 2·
`\pi`·radius·height

But she only wants to fill half, so divide by 2, cancels the 2 in the formula for volume, giving us:
`\pi`·radius·height

`\pi`·2·0.75 = 4.71 feet³
