Question

Olga is installing a fence around her circular pool. The radius of the pool is 7 feet. How many feet of fencing material will she need? [ Use pi = 22/7] *

Answer 1

Ok, to find the feet of fencing material that she need we need to calculate the perimeter of the circle.

We are going to use the folling formula:

`\text{Perimeter}=2\pi r`

So, replacing:

`\text{Perimeter}=2((22)/(7))\cdot7`
`=(44)/(7)\cdot7=44`

She need 44 feet of fencing material.
