The equation for finding the circumference of a circle is diameter times pi so reverse it to circumference divided by pi which leaves the diameter. The diameter is twice as big as the radius so divide the diameter by 2 and you will find the radius.
The formula for the circumference of a circle is pi * diameter or (2 radius.)
Radius is 1/2 of a diameter. 2.5/2 is 1.25. Radius is necessary in finding the circumference and area of a circle.
circumference of a circle = 2*pi*radius or pi*diameter
the equation for the circumference of a circle is 2*radius*pi, or since the radius is half of the diameter 2*radius=diameter, we can simplify the equation to the circumference of a circle=diameter*pi
If you have the circumference: circumference = (pi) * diameter diameter = circumference / (pi) If you have the area: area = (pi) * radius * radius radius = square_root(area / pi) radius = diameter / 2 diameter = 2 * square_root(area / pi)

They both use pi:- circumference = 2*pi*radius or diameter*pi area = pi*radius2
The diameter and radius of a circle if the circumference is 37.68 are:Diameter = 11.99Radius = 5.997
radius is half the diameter of a circle.
The circumference of a circle equals the diameter times pi. The diameter is two times the radius. So a circle with a radius of 6 would have a diameter of 12, and a circumference of 12pi.
Circumference of a circle = 2*pi*radius or diameter*pi
The diameter of any circle is twice its radius.
