It feels a lot like two people arguing about which is the best way to calculate the circumference of a circle: multiply the diameter of the circle times pi (C = pi*d) or double the radius and then ... argue that the first formula is best, because it ...Pi week: going full circle - Part II

Consider a circle that is 1 foot in radius (from the center to the outside). Then this circle must be 2 feet in diameter. Using our formula for the circumference, C = d x pi, gives us a circumference of 2 x pi. But how would we measure this?
