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
