"Pi 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. It is approximately equal to 3.14159 in the usual decimal notation. Pi is one of the most important mathematical and physical constants: many formulae from mathematics, science, and engineering involve pi." -Wikipedia
