$\pi$

Answer 1

Answer:

Pi is a mathematical constant whose value is the ratio of a circle's circumference to its diameter (Pi = C/d). Pi is an irrational number, meaning it cannot be referenced exactly as a fraction, but only as a decimal which never ends or repeats.

The reasonm it is called pi is because the symbol used by mathematicians to represent the ratio of a circle's circumference to its diameter is the lowercase Greek letter π, sometimes spelled out as pi, and derived from the first letter of the Greek word perimetros, meaning circumference.
