Determining diameter from circumference
WebIf you know the diameter or radius of a circle, you can work out the circumference. To begin with, remember that pi is an irrational number written with the symbol π. π is roughly equal to 3.14. The formula for working out the circumference of a circle is: Circumference of circle = π x Diameter of circle. This is typically written as C = πd. WebThe following equations show how the radius and diameter relate to the circumference. The equation for circumference of a circle is: c=\pi d c = πd. If written instead in terms of the radius, the circumference calculation is instead: c = 2 \pi r c = 2πr. Dimensions of a circle: O - origin, R - radius, D - diameter, C - circumference ( Wikimedia)
