WEBJul 20, 2023 · To calculate the circumference of a circle, use the formula C= pi*D where C is the circumference, D is the diameter and pi is 3.14. If you have the radius instead of the diameter, multiply it by two to get the diameter. You can also use the formula for the circumference of a circle using the radius which is C equals 2 pi R where R is the radius. Views: 10M

WEBThe circumference of a circle is calculated using the formula: 2 x π x radius, where π is a mathematical constant, equal to about 3.14159. It was originally defined as the ratio of a circle's circumference to its diameter (see second formula below on why) and appears in many formulas in mathematics, physics, and everyday life.

WEBCircumference of a circle formula: There is a specific relationship between the diameter of a circle and its circumference. If you multiply the diameter of a circle by \pi π, you will calculate the length of the circumference. This is true of all circles. Therefore this formula can be used to find the circumference of any given circle:
