Pi (π) is the mathematical constant that represents the ratio of a circle’s circumference to its diameter. It can be demonstrated that this ratio remains the same no matter how large or small the circle is: approximately 3.14159.
I recently became passionate about Pi, started to read a lot about this number, and decided to share my discoveries on this blog.
In addition to Pi-related tools, such as a Pi Digits learning game, a circle calculator and a sphere calculator, you will find here Pi-related articles that I will update regularly.
