Question

Circle O has a circumference of 88π cm.
Circle O has a radius length of r.

Answer 1

r = 44 cm

Explanation:

A circle has a circumference of 88π cm . The circumference of a circle is the distance around a circle. The radius can be calculated as follows.

circumference = 2πr

where

r = radius

circumference = 88π

circumference = 2π × r

88π = 2πr

divide both sides by 2π

r = 88π/2π

r = 44 cm

Answer 2

The radius r of the circle is 44cm

Explanation:

This problem bothers on the mensuration of flat shapes, a circular shape.

Given data

Circumference of circle C= 88πcm

Radius of circle r=?

The problem seeks to solve for the radius r.

To solve for the radius let us apply the formula for the circumference of a circle

C=2πr

Substituting our given data

88π=2πr

Making r subject of formula we have

r= 88π/2π

r= 44cm
