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?
You have to start by finding the diameter from the circumference. The formula for circumference is C=[tex] \pi D[/tex]. C is the circumference and D is the diameter.
132ft=[tex] \pi D
[/tex] and your looking for D
Your first and only step is to divide 132ft by[tex] \pi [/tex]. [tex]132/ \pi =D[/tex]
D=42ft
Radius is half of the diameter or D. To find the radius you have to divide D by 2.
