Question

A gardener is installing a circular garden. The radius of the circle 28 feet. He needs to know the circumference in order to buy materials for the edging. What is the circumference if he uses = 22/7?

Answer 1

The circumference would be 176 feet. The equation for circumference is diameter x pi. Since the radius is 28 the diameter would be twice that.

Answer 2

`C=176\ ft`

Explanation:

we know that

The circumference of a circle is equal to

`C=2\pi r`

where

r is the radius of the circle

In this problem we have

`r=28\ ft, \pi=22/7`

substitutes

`C=2(22/7)(28)=176\ ft`
