How do i find circumference of a circle
WebJul 3, 2024 · You can calculate the circumference of any circle if you know either the radius or diameter. The formulas are: C = πd C = 2πr where d is the diameter of the circle, r is its radius, and π is pi. So if you measure the diameter of a circle to be 8.5 cm, you would have: C = πd C = 3.14 * (8.5 cm) C = 26.69 cm, which you should round up to 26.7 cm WebOct 23, 2011 · The equation for the circumference of a circle can be written in two ways: C = 2πr. C = πd. Where: r represents the radius of the circle, and d represents a circle's diameter. Recall that the radius is the distance from the center of the circle to a point on the edge of a circle, and the diameter is the largest distance across a circle.
