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.
