Circle O has a circumference of 88π cm.

Circle O has a radius length of r.

r = 44 cm

Step-by-step 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

The radius r of the circle is 44cm

Step-by-step 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
