Formula to Calculate Perimeter of a Circle
The perimeter of a circle is the distance around the edge of the circle. The formula to calculate the perimeter of a circle is:
P = 2πr
- P represents the perimeter of the circle
- π represents the mathematical constant pi (approximately equal to 3.14)
- r represents the radius of the circle
Explanation
The perimeter of a circle is the total distance around the outside of the circle. The formula for the perimeter of a circle uses the radius of the circle, which is the distance from the center of the circle to any point on the edge of the circle. The formula multiplies the radius by 2π, which is the ratio of the circumference of a circle to its diameter. The result is the total distance around the edge of the circle.
Example
Let's say we have a circle with a radius of 5 cm. Using the formula, we can calculate the perimeter of the circle:
P = 2πr
P = 2 x 3.14 x 5
P = 31.4 cm
Therefore, the perimeter of the circle with a radius of 5 cm is 31.4 cm.
