Amanda's family has a swimming pool that is 4 feet deep in their backyard. If the diameter is nearly 25 feet, what is the circumference of the pool?

Express your answer to the nearest whole foot.

The formula for finding circumference is Pi multiplied by diameter.

3.14 x 25ft = 78.5 feet

This would round up to 79 feet in circumference.

79 ft

Step-by-step explanation:

The formula for the circumference of a circle is

C = 2πr. If it's the diameter that is known, then C = πd. We will use the latter formula to find the circumference of this pool:

C = π (25 ft) = 78.54 ft, approx., which, to the nearest foot, is 79 ft
