The formula for the circumference of a circle is the same, whatever its diameter. Circumference = pi*diameter.

Formula of Circumference of a circle: 3.14*Diameter of the circle. You could also do: 3.14*3.14*radius.

The formula; 2 * Pi * Radius = circumference Will calculate the circumference of a circle.

Circumference of a circle = 2*pi*radius

A simple formula to calculate the circumference of a circle: so in this case:
