Circumference and area of a circle formula
WebOnce you have the radius you times the radius by 2 and times it by pie and then you get the circumference. Here are the two different formulas for finding the circumference: C = πd … WebA = C [set area equal to circumference] πR2 = 2πR [use formulas for area and circumference of a circle] R2 = 2R [divide both sides by π] R2 – 2R = 0. R (R – 2) = 0. So the solutions are R = 2 and R = 0. The first solution, R = 2, gives us a circle with an area of 4π square units and a circumference of 4π linear units.
