The formula for the circumference of a circle given it's radius is :

C = 2πr

Reversely, the formula for the radius given it's circumference is :

r = C/2π

From the given problem, the circumference is 63 inches,

Solve for the radius using π = 3.14

r = 63/(2 x 3.14)

r = 10.03 inches

So the answer is Choice C. 10 inches
