Well, we know that if a circle has a diameter of 1, the circumference is pi, and we also know that the radius is 1/2 of the diameter, so we multiply the radius (56) by 2 to get 112, which we multiply by pi to get the circumference. So, we could either assume pi is 3.1415926, or we could express this number as 112π units, or as 351.858371 units.
