Master The Calculation Of Circumference: Formulas, Examples And Tips

Circumference of a Circle

c=2 x pi x r OR pi x D

The circumference of a circle is the distance around its edge or perimeter. It is measured in units of length such as cm, meters, feet, etc. The formula to calculate the circumference of a circle is given by:

Circumference = 2 x π x r

Where π is pi (a mathematical constant equal to approximately 3.14) and r is the radius of the circle.

Alternatively, we can use another formula to find the circumference of a circle if we know its diameter (d) rather than its radius. That formula is:

Circumference = π x d

In this formula, the diameter (d) is the distance across the circle, passing through its center and touching both edges.

To find the circumference of a circle, we simply plug in the given value of either the radius or diameter into the appropriate formula and solve for the circumference. The resulting value will be in the same units as the given radius or diameter.
