How do you find the radius of a circle with a circumferance of 70 inches?
divide the circumference by 3.14 to get the diameter - then divide that by 1/2 to get the radius Radius = Circumference / 2 x pi from C = Diameter x pi
A circle has a curcumference that measures 18pi inches. What is the radius in inches of the circle?
Circumference equals 2 X pi X radius, so work backwards. 18pi=2 X pi X radius divide pi. 18= 2 X radius divide by 2. radius= 9.
How do you find the radius and diameter when they give you a circumference?
divide the circumference by pi ( 3.146) which will give you the diameter divide that by 2 and you have the radius
