Oct 2, 2024 · To find the perimeter of any circle, multiply the diameter by the number pi (π). In this case, 10 in × π = 31.416 in. This circle perimeter calculator finds the perimeter (p) of a circle if you know its radius (r) or its diameter (d), and vice versa.

The perimeter of a circle is the distance around its outer edge. The formula for finding the perimeter of a circle is: P = 2\pi r P = 2πr. where P is the perimeter, π (pi) is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.
How To Calculate Radius Using Perimeter of Circle Formula? The perimeter of circle formula = 2πr units. If we know the value of the circumference or the perimeter of a circle, then by substituting the value in formula we can calculate radius.
Radius: the distance between any point on the circle and the center of the circle. It is equal to half the length of the diameter. Diameter: the largest distance between any two points on a circle; by this definition, the diameter of the circle will always pass through the center of the circle.
The formula used to calculate the perimeter of a circle, which is also known as the circumference, is: C = 2πr. Where: C represents the circumference. π is a constant approximately equal to 3.14159. r represents the radius of the circle.
Jul 31, 2024 · For example, a circle with a 5 cm radius will have a 10 cm diameter and a 31.4159 cm circumference. The calculator also gives the area of this circle to be 78.5398 cm². We can also use the calculator in reverse — i.e., to find the radius of a circle from its circumference.
The perimeter of a circle is calculated using the formula 2 x Pi x Radius, or Pi x Diameter. Diameter = 2 x Radius. The radius of a circle is the length of the line from the center to any point on its edge. The diameter is defined as twice the length of the radius of a circle.
