Question

A round plastic wading pool has diameter 5 FEET. It is filled with water to a depth of 6 INCHES. What is the volume of water in the pool? Round to one decimal place and include unit.

Answer 1

To find the volume of water in the pool, we would find the area of the pool's surface and multiply it by the depth of the pool. The area of the pool's surface would be determined by the formula,

Area = pi x radius^2

From the information given,

diameter = 5

recall,

radius = diameter/2

Thus,

radius = 5/2 = 2.5

depth = 6 inches

We would convert from inches to feet

Recall,

12 inches = 1 foot

6 inches = 6/12 = 0.5 foot

Thus, depth = 0.5

pi = 3.14

Thus,

Area = 3.14 x 2.5^2 = 19.625

Volume = 19.625 x 0.5 = 9.8125

Volume of water in pool is 9.8 cubic feet to 1 decimal place
