Circumference = πd diameter = 2 x radius
To find the circumference of a circle, use the equation: Circumference = 2*π*radius so when the radius is r, the circumference is 2πr
The circumference of a circle is equal to the radius times 2*pi. 2*pi*R where R is the radius.
Circumference of a circle with radius 'r' = 2(PI)(r) ~ 6.28(r)
The radius of a circle is the distance from its centre to its circumference. If a circle has a radius of r units then the length of its circumference is 2*pi*r units.
