Question

A zoo has a circular pool for its seals. The diameter of the pool is 32 feet. How much fence is needed to enclose the pool?

Answer 1

The answer is
`32 \pi\ feet` or
`100.53\ feet`

Explanation:

we know that

To calculate how much fence is needed to enclose the circular pool, find the circumference of the circular pool

The circumference of a circle is equal to

`C=\pi D`

where

D is the diameter of the circle

In this problem we have

`D=32\ feet`

Substitute

`C=\pi (32)=32 \pi\ feet`

`C=32 \pi\ feet=100.53\ feet`
