Question

A gardener is installing a circular garden. The circumference of the circle 132 feet. What radius should he use to layout the circle if he uses p=22/7?

Answer 1

You have to start by finding the diameter from the circumference. The formula for circumference is C=
`\pi D`. C is the circumference and D is the diameter.

132ft=
`\pi D` and your looking for D

Your first and only step is to divide 132ft by
`\pi`.

`132/ \pi =D`

D=42ft

Radius is half of the diameter or D. To find the radius you have to divide D by 2.

R=42/2

R=21ft

The radius is 21ft
