Question

Solve this problem using the proper formula

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

Given that the garden should be in a circular shape.

And the circumference of the circle would be, C = 132 feet.

It says to find the radius of the circular garden, r = ?

We know the formula for Circumference of the circle is given as follows :-

Circumference of circle = 2π x radius

C = 2·π·r

Hint:- It says to use pi = 22/7.

Hence, Radius would be r = 21 feet.

Answer 2

C = 2πr
132 ft = 2(22/7)r
r = (132 ft)*7/44 = 21 ft

The radius is 21 feet.
