WebThe 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. This tells us that the … WebThe equation for diameter of a circle from circumference is: d=c/\pi d = c/π. If written instead in terms of the radius, the diameter is very simple; it's just twice as long: d = 2r d = 2r. Dimensions of a circle: O - origin, R - radius, D - diameter, C - circumference ( Wikimedia) Area is the space contained within the circle's boundaries.
