Who or what is this Pi? This question some thinkers tried to solve even before antiquity. Mathematicians and researchers ventured from time to time and step by step more and more to the explanation of the infinite number Pi. The first mathematician who was able to mathematically narrow down this number was Archimedes in 250 BC.
But what does this particular number do now? What did she mean? Pi describes the ratio of circumference to diameter, starts with 3.1415926535… and goes infinitely far. This ratio is independent of the size of the circle. The number Pi is also irrational and has no finite or periodic decimal representation. The circle number is also a fundamental component in the calculation of the circumference and area of circles.
What is Pi in simple terms?
The circle number Pi has the symbol π. It is a mathematical constant that describes the ratio between the circumference of a circle to its diameter. We need this number in all sorts of formulas around circular calculations, but also in other areas of mathematics and physics.
A distinctive feature of π is that it is irrational. It cannot be represented by a fraction of two integers. Furthermore, π has infinitely many decimal places and has no unit.
