Question

Joe needs to put a fence around the perimeter of a circular pool. The radius of the pool is 14 feet. How much fencing will Joe need to surround the entire pool? Leave your answer in terms of π.

Answer 1

28
`\pi` feet

Explanation:

Find how much fencing he will need by finding the pool's circumference:

Use the circumference formula, C = 2
`\pi`r

C = 2
`\pi`r

C = 2
`\pi`(14)

C = 28
`\pi`

So, Joe will need 28
`\pi` feet of fencing
