Why does PI exist?
Pi exists because circles exist. Draw a circle of whichever size, measure its circumference, and then divide that value with the length of its diameter. The value so obtained is always a constant (as long as the measurements are accurate) and is called pi.
What is so special about pi?
Formally, 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 (ie, it’s “transcendental). …

What if PI were 3?
Hamlin said if Pi really were 3.2 or 3, it would mean Pi was a rational number. Rational numbers include fractions, counting numbers, negative numbers, numbers with decimals that end (ex: 3.0374), and numbers with decimals that repeat (ex: 0.33333).
