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.

Respuesta :

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.

Answer:

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
