The number π ( p aɪ ⓘ; spelled out as pi) is a mathematical constant, approximately equal to 3 14159, that is the ratio of a circle's circumference to its diameter It appears in many formulae across mathematics and physics, and some of these formulae are commonly used for defining π, to avoid relying on the definition of the length of

Pi (π) ( p aɪ ) is a mathematical constant that is the ratio of a circle's circumference to its diameter This produces a number, and that number is always the same However, the number is rather strange The number starts as 3 141592653589793 and continues without end Numbers like this are called irrational numbers [1] [2] [3]

There are many simulations and statistical techniques that can be used to approximate \(\pi\) Long before computers were invented, the French mathematicians Buffon \((1707-1788)\) and Laplace \((1749-1827)\) proposed using a stochastic simulation to estimate the value of \(π\)
