The Circumference (C) {the outside ring) of a circle equals 2 Pi's (Pi=3.14){2 Pi=6.28} multiplied by the Radius (R) {half way through the middle of the circle}.
Hope that helps! :-) If I got it wrong, someone smarter them me should correct me. But I'm pretty sure that's right.

What is the radius of a circle with circumference of 8 inches?
C = 2*pi*r 8 = 2*pi*r 4 = pi*r r = 4/pi
The circumference of a circle is 60 pi cm what is the radius of the circle?
let c bet the circumference and r be the radius. c = 2 pi r since c is 60 pi 60pi = 2 pi r divide both sides by 2 pi 30 = r
Can the circumference and the area of a circle both have the same answer?
C=2(pi)r A=(pi)r2 If C=A, then 2(pi)r=(pi)r2. Divide both sides by r: 2(pi)=(pi)r. Divide both sides by (pi): 2=r. Therefore, if the radius of a circle is 2 ft., the circumference is 2 sq. ft.
What is the circumference of radius equals 90 FT?
C = pi*r82 C = Pi*r*2 90=R Thus 180*Pi
What is the formula to find a radius when given the cicumference?
circumference=pi * diameter radius= 1/2 diameter
