Answer:

The answer to your question is 10 in

Step-by-step explanation:

Data

Circumference = 20π in

Radius = x

Formula

Circumference = πd

Process

1.- Equal the formula to the circumference

            πd = 20π

2.- Solve for d

               d = 20π / π

3.- Simplification

               d = 20

4.- Find the radius

               r = d/2

               r = 20/2

               r = 10 in
