Using an infinite series shown by Euler, 𝜋 can be approximated.
The series goes as follows: \sum\limits_{n=1}^{\infty}\frac{1}{n^2}=\frac{1}{1^2}+\frac{1}{2^2}+\frac{1}{3^2}+\frac{1}{4^2}+\dots=\frac{\pi^2}{6}
By rearranging the equation, you get the following: \pi=\sqrt{6\cdot\big(\frac{1}{1^2}+\frac{1}{2^2}+\frac{1}{3^2}+\frac{1}{4^2}+\dots\big)}
