Pi is an irrational number, can not be represented as a fraction or repeating or terminating decimal, therefore to write it as a number it must be rounded off or estimated.
Many formulas can cancel or reduce out the value for pi and make for short work of the number.
Pythagoras was the 1st person who used the pi symbol first
it is a number 3.14159265358979323846264338327950288... it's just a lot of numbers after that
in terms of pi- when using the symbol for pi instead of 3.14 or 22/7 in the end result of an equation
Any mathematician will use the number pi (and its symbol) sooner or later - it is a number used extensively in many different areas of mathematics.
Archimedes first used the symbol PI because he was the first one to discover it so he wanted to investigate about it.
The first time the symbol Pi was first used for Pi was in ancient Greece in their numbers. The symbol "π" was number 80 in Greece.

The pi symbol was introduced in 1706 by William Jones. The usage of the symbol was popularized by Leonhard Euler. He adopted it in 1737.
The symbol for pi is the 16th letter of the Greek alphabet. Many Greek letters are used in mathematics for various functions.
