WebThe formula is S = r θ where s represents the arc length, S = r θ represents the central angle in radians and r is the length of the radius. Demonstration of the Formula S = r θ The interative demonstration below illustrates the relationship between the central angle of a circle, measured in radians, and the length of the intercepted arc. WebPi is the ratio of circumference over diameter. 2 and r come from the formula of diameter. You have to find circumference of a circle. Pi comes here because of its ratio. 2 and r comes because it equals the diameter. So pi times 2 times r is basically circumference over diameter times diameter which gives circumference.
