(pi)D=30
30/3.14 = D
(18-(30/3.14))/2
4.23 inches

Lets find the radius of the basketball
2pi*r = 30 formula for circumference
r = 4.775 inches
We know the diameter of the rim is 18 inches, so the radius is 9 inches
so we subtract the two radii
9 - 4.775 = 4.2 inches is the clearance all the way around.
