Answer:
The diameter of the circle is [tex]D=36\ in[/tex] and the radius is [tex]r=18\ in[/tex]
Step-by-step explanation:
we know that
The circumference of a circle is equal to
[tex]C=\pi D[/tex]
where
D is the diameter of the circle
we have
[tex]C=113.04\ in[/tex]
substitute and solve for D
[tex]113.04=(3.14)D[/tex]
[tex]D=113.04/(3.14)[/tex]
[tex]D=36\ in[/tex]
Find the radius r
[tex]r=36/2=18\ in[/tex] -----> the radius is half the diameter
