If you mean the diameter and radius of a circle given the circumference it is:- diameter = circumference/pi radius = circumference/(2*pi)

To find the circumference of a circle the formula is: 2*pi*radius or diameter*pi

circumference=pi * diameter radius= 1/2 diameter

divide 3.14 by circumference and d=2r

Diameter = radius * 2 Circumference = pi * diameter.

the Circumference is pi times 2 times radius If you know circumference then you can find the radius. once you know the radius just multiply by 2 to find the diameter.

Easy. First, double the radius to get the diameter. Next, multiply the diameter by Pi (about 3.1416) to determine the circumference.

circumference of a circle = 2*pi*radius or pi*diameter

Circumference is pi * diameter, or pi * 2 * radius, so if you are given circumference, then radius = circumference / 2 / pi. Pi is approximately 3.1416 Radius is from the center to the edge. Diameter is twice that (from one edge, through the center to the other edge). Radius = Diameter / 2, so if you're given Diameter, then just divide by 2.

Diameter of a circle = 2*radius Circumference of a circle = 2*radius*pi

circumference=2(pi)r so divide the given circumference on 2pi, it will give radius. Now multiply radius by 2 you will get the diameter.

If the circumference or diameter is given then you can find the radius or simply measure the distance from the centre of the circle to the circumference.
