Answer:

The diameter of the circle is
$D=36\ in$ and the radius is
$r=18\ in$

Explanation:

we know that

The circumference of a circle is equal to

$C=\pi D$

where

D is the diameter of the circle

we have

$C=113.04\ in$

substitute and solve for D

113.04=(3.14)D

D=113.04/(3.14)

$D=36\ in$

Find the radius r

$r=36/2=18\ in$ -----> the radius is half the diameter
