Diameter = circumference/pi
Radius = circumference/2*pi
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
Easy. First, double the radius to get the diameter. Next, multiply the diameter by Pi (about 3.1416) to determine the circumference.
Diameter = radius * 2 Circumference = 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.
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
divide 3.14 by circumference and d=2r
C = pi d By algebraic rearrangement d = C / pi
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=2(pi)r so divide the given circumference on 2pi, it will give radius. Now multiply radius by 2 you will get the diameter.
Diameter of a circle = 2*radius Circumference of a circle = 2*radius*pi
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.
pi X diameter finds the circumference so circumference divided by pi will leave the diameter. half the diameter to find the radius
