By definition, pi is the ratio of the circumference of a circle to its diameter. Pi is always the same number, no matter which circle you use to compute it. For the sake of usefulness people often need to approximate pi.
Pi (symbol Ï) is a mathematical constant whose value is the ratio of any circle's circumference to its diameter in Euclidean space; this is the same value as the ratio of a circle's area to the square of its radius.(Area of a circle = Ïr2). This number is the same for every circle.i is the ratio of the circumference of a circle to its diameter. Ï is an irrational number, which means that its value cannot be expressed exactly as a fraction, Consequently, its decimal representation never ends or repeats.
