If the sum of the circumferences of two circles with radii R1 and R2 is equal to the circumference of a circle of radius R, then R1 + R2 = R. Explanation: According to the question, Circumference of circle with radius R = Circumference of first circle with radius R1 + Circumference of second circle with radius R2 $\therefore$ 2$\pi$R = 2$\pi$R1 + 2$\pi$R2 $\Rightarrow$ R = R1 + R2
