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 (/ËpaÉª/; Greek: [pi], uppercase Ï, lowercase Ï) is the sixteenth letter of the Greek alphabet, representing [p]. In the system of Greek numerals it has a value of 80.
