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

How much fence is needed to enclose the pool is called the circumference or perimeter of a circle.


`c = \pi * {r}^(2)`

In this case we got the Diameter which is equal to 2 times the radius

`r = 32 / 2 \\ = 16`
UNTO THE EQUATION

`c = 3.14 * 16 \\ = 50.24ft`
Therefore you would need 50.24 feet of wire to fence it!
