The radius is Half of the Diameter. So you would do 8/2 = 4

r=4
Answered by Guido
diameter = 2 times radius

In other words, it takes 2 radii to make one diameter.

You are given the diameter to be 8 inches.

We have:

8 inches = 2r

We divide both sides of the equation by 2 to find r.

8 inches/2 = r

4 inches = r

Let r = radius.

Then, radius is 4 inches.

Done!
