The answer depends on what R and C are.
If: C = 2r Then: r = C/2
p = r - c r - c = p r - c - r = p - r -(-c) = -(p) c = -p
p+c=r.

The answer depends on what R and C are.
C=2(pi)(r) therefore if r equals 3.20 then C=20.1061929
If: C = 2r Then: r = C/2
p = r - c r - c = p r - c - r = p - r -(-c) = -(p) c = -p
p+c=r.

The circumference of a circle C is 2Pixr So solving for r we have C/2Pi=r
-9
3 equals rings in a circus
7=c(s) obviously
Presumably C means circumference and R means radius? If C = 2*pi*R Then R = C divided by 2*pi
If: -7 = 7-2r Then: r = 7
