Circumference related to diameter
WebThe circumference (C) of a circle with radius R is given by the equation C = 2πR To find out when the area has the same value as the circumference, we must set the area equal to the circumference and solve for R: A = C [set area equal to circumference] πR2 = 2πR [use formulas for area and circumference of a circle] R2 = 2R [divide both sides by π] WebThe radius, diameter, and circumference of a circle are all related through the mathematical constant π, or pi, which is the ratio of a circle's circumference to its …
