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?

the radius is ____ feet.?

Answer 1

the radius is 21 feet

Answer 2

The radius is 21 feet.

Explanation:

Consider the provided information.

It is given that the circumference of the circle 132 feet.

The circumference of the circle can be calculated as:
`2 \pi r`

Where r is the radius of the circle.

Thus,

`2 \pi r=132`

`\pi r=(132)/(2)`

`\pi r=66`

Substitute the value of π=22/7 in above equation.

`(22)/(7)r=66`

`r=(7)/(22)* 66`

`r=7* 3`

`r=21`

Hence, the radius is 21 feet.
