Approximations of π

ID: approximations-of-pi

Approximations of π (pi) refer to the various methods and numerical values that estimate the mathematical constant π, which represents the ratio of a circle's circumference to its diameter. Since π is an irrational number, it cannot be expressed exactly as a simple fraction, and its decimal representation is non-repeating and infinite. However, various approximations have been developed throughout history for practical calculations.
