C = 2π × r
- The circumference of a circle is equal to the length of its boundary, but the circle is a curved shape, its circumference can’t be measured with a ruler. The correct way to find the perimeter of a circle is to calculate it using the formula C = 2π × r.

The perimeter of a circle is called the circumference. To find the perimeter of a circle, follow these simple steps: find the diameter of the circle (the distance from one side to the other in a straight line through the middle) multiple the diameter by pi (or π)
The circumference of a circle is the measurement of how far the distance goes around the circle. We can think of it as the “perimeter” of the circle because it is literally the measure of the length of the circle’s boundary.
