Question

A circular swimming pool is 28 feet in diameter. How many feet around the pool?

Answer 1

28π ft 87.96 ft

Explanation:

This question is asking for the swimming pool's circumference, or its perimeter. To find this, use the formula C = dπ.

C = 28π ft

This can also be approximated as 87.96 ft.

Answer 2

Approximately, 87.1

Explanation:

C=2πr=2·π·14≈87.96459

Keep in mind, remember to find the radius.

28 feet is diameter, half of that is 14.

So r = 14.
