Key concepts about circle perimeter
The perimeter of a circle, also known as circumference, is the total distance around a circle. It is calculated with the following mathematical formula:
P = 2 × π × r
Here, r represents the radius of the circle and π (pi) is a mathematical constant with an approximate value of 3.1416. This calculation is essential in areas such as geometry, engineering, and design, allowing precise measurements in construction, manufacturing, and other applications.
For example, if a circle has a radius of 7 cm, its perimeter would be calculated as follows:
