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 (/paÉª/, paÉª).
Pi is a number expressing the ratio of the circumference of a perfect circle to its diameter. As there are no perfect circles or spheres in nature (since matter is composed of atoms and is therefore not smooth) the continued extension of pi has long been seen as a harmless exercise of computer power.
