The symbol used by mathematicians to represent the ratio of a circle's circumference to its diameter is the lowercase Greek letter Ï, sometimes spelled out as pi, and derived from the first letter of the Greek word perimetros, meaning circumference. In English, Ï is pronounced as pie (/ p aÉª /, paÉª).
