Question

The Ming family has a backyard kiddie pool with dimensions 2 ft×4 ft. After a lot of splashing one afternoon, the pool is only half full. What is the volume of water remaining in the pool? Either enter an exact answer in terms ofπ or use 3.14 for π. Express your answer in cubic feet

Answer 1

We can see here that the the volume of water remaining in the pool is 8π ft³.

If we assume the pool is actually a cylinder with a radius of 4 ft and a height of 2 ft, we can use the formula for the volume of a cylinder, which is V = πr²h, where r is the radius and h is the height.

Given that the radius is 4 ft and the height is 2 ft, we can plug these values into the formula:

V = π(4 ft)² × 2 ft

V = 16π ft³

Now, we need to find half of this volume since the pool is only half full.

Half of 16π ft³ is equal to (16π ft³) / 2, which simplifies to 8π ft³.

Therefore, the volume of water remaining in the pool is 8π cubic feet.
