C = 2*pi*r 8 = 2*pi*r 4 = pi*r r = 4/pi
C=pi x 2 r C/2pi=r 8/6.28=1.27
The formula where C=circumference, R=radius is C = 2 pi R Since C = 16 pi inches and 16 pi = 2 pi R we can solve for R and get R= 16 pi /2 pi = 8 Therefore the Radius is 8 inches.

If r = 8 inches then C = 50.27 inches.
p = r - c r - c = p r - c - r = p - r -(-c) = -(p) c = -p
C - i - v - i - l w - a - r
C=2Pir, since r is 8. the answer would be 16pi.
