Circumference related to diameter
WebJun 14, 2024 · Mathematicians discovered years ago that all circles have one thing in common: the ratio of the circumference of a circle to its diameter (circumference/diameter) is a constant number called pi ... 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]
