Dividing the circumference of a circle by its diameter.

Explanation:

#pi# is found when you divide the circumference (c) or the perimeter of a circle by its diameter (d) or two times the radius (r). It is literally the ratio of one to the other, no matter the size of the circle. So:

#pi=c/d=c/(2r)#
