PI (Π) was never made. It was used to describe an idea.

Pi is an real number which when multiplied by the radius of a circle squared will provide you with the area of the circle. Or when multiplied by the diameter will give you the circumference.

It has been used since Egyptian times and is a valuable number, the decimal expansion of which has never been fully calculated and never will be, because it never ends. It is approximated by 3.14159265358979323846264 to what I can remember from my school days.
