Hello you aliens! Welcome to another blog on one of the most famous symbols in the world of mathematics. That is Pi ( π ). We all know that Pi is defined as the ratio of the circumference to the diameter of the circle, and is numerically equal to 3.141592653589793238...... and so more. But here we have more interesting facts about Pi that most of you might not be aware of.Lets have a look on them. 1. Pi ( π ) is an irrational number. That means, it cannot be expressed as a fraction of two integers (p/q, where q is a non zero integer). In the 1760s, Johann Heinrich Lambert proved that the number π ( pi ) is irrational. Its an endless number, where you can find about 200 millions digits of Pi. You need a bit mathematical knowledge to understand the image below. 2. We all know that we generally use 22/7 as value of Pi. But, u should know that exact value of Pi is not equal to 22/7 but it is less than 22/7 ...
Hello people ! Happy reading ahead :)
