pi is the ratio between the radius and the circumference of the circle if the radius is 1 the circumference is pi
The circumference of any circle when divided by its diameter has the exact value of pi
Pi is the number you get by dividing a circle's circumference by its diameter. It is irrational. It is 3.1415926535897. Every generation, people figured out another few didgets of pi.

pi is a mathematical formula, or 3.14159265389793238462683. it relates to the diameter and circumference of a circle. i don't know the history but im sure its somwhere!answ2. There is currently a proposal to name 2 Pi as Tau, as this aids in many calculations. Watch this space. The ratio of the perimeter to the height of Khufu's Pyramid is 2 Pi.

The history of pi dates back to ancient civilizations, such as the Babylonians and Egyptians, who approximated the value of pi. The first accurate calculation of pi was made by the Greek mathematician Archimedes in the 3rd century BC. The symbol for pi was introduced by the Welsh mathematician William Jones in the 18th century, and it has since become one of the most important mathematical constants in mathematics.
it came from Sir Alan Pi in 1898. he died 1 day after discovering it through being sniped by a Barrett .50cal
