Sumerians and Babylonians all had estimates of π accurate to one decimal place (although their approximations were different and found by different methods). The Bible also has a claim to an ...

Clearly, then, there must be other ways to calculate π that give more digits accurately and quickly. But why should we bother, especially since the old approximation π ≈ 22/7 = 3.14 ...

Pi Approximation Day celebrates the pi symbol (π) and its importance to mathematics. The symbol is a Greek letter, and it is used in mathematics to represent the ratio of the circumference of a ...

It commemorates the common approximation of the mathematical constant π as 22⁄7, which dates back to Archimedes and provides an accuracy of two decimal places. While many people celebrate March ...
