Problem Statement

We might We always use π (Pi) in our everyday life, but we merely have an idea about its history or origin not have a complete idea about its use in different areas

Scopes
Studying authentic books, articles, and online resources to identify the properties of π (Pi)
Collecting different sources about the history of π (Pi) across the world
Understanding the use of π (Pi) in different areas of study

What is π (Pi)

The ratio of a circle’s circumference to its diameter is a constant, this constant called π (Pi). It represents by the Greek letter π .

If C be the circumference and D be
the diameter of a circle, than π(Pi) = C/D

Value of π (Pi) is 3.141592653589793….…..

History of π (Pi)

From ancient Babylonia to the middle ages in Europe to the present day
of supercomputers, mathematicians have been striving to calculate the
mysterious number.

Based on time span we can divide the history of π (Pi) by

1. The Early History of Pi (π): 2000 BC to 1500 AD
2. The Modern History of Pi (π):16th Century to Present

BC: Before Christ & AD: Anno Domini (Booth are used in the Gregorian Calendar)

Early History

π (Pi) Bible: “Also he made a molten sea of ten cubits(A cubit is an ancient unit of length) from brim to brim, round in compass, and five cubits the height thereof and a line of thirty cubits did compass it round about” .

This implies that Pi (π) = 30/10

π (Pi) in Egypt(1650 BC ) :

Egyptian Mathematicians gives another ancient estimation for pi that is “Cut off 1/9 of diameter and construct a square upon the remainder; this has the same area as the circle”.

In other words, he implied that Pi (π) = 4(8/9)2 = 3.16049, which is also fairly accurate.
