Circumference of a Circle
Formula:C = 2 × π × r
Introduction to Circumference of a Circle Calculator
The circumference of a circle is calculated by multiplying its radius by 2 and then by π. In this formula, C represents the circumference of the circle, and r is the radius of the circle. The result is expressed in the same units as the radius.
Parameter usage:
radius
= radius of the circle
Example valid values:
radius
= 5
Output:
circumference
= circumference of the circle
Data validation
The number should be greater than or equal to zero.
Summary
