Formula For Diameter Of A CircleThe first one is based on the radius of the circle. The diameter equals the length of two radiuses. d = 2 r d=2r d = 2 r. Area of a circle: d = 2 A π d=2\sqrt{\frac{A}{π}} d = 2 π A Circumference of a circle: d = c π d=\frac{c}{π} d = π c where: r r r stands for the radius of the circle, c c c for circumference, A A A for area, and; d d d . The different ways to calculate the diameter of a circle are given below If the radius of a circle is known the diameter is calculated as D 2R Where R is the radius of the circle If the circumference of a circle is known then the formula to calculate the diameter is D C Where C is the circumference of a circle
