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. In English, Ï is pronounced as pie (/paÉª/ , paÉª).till, fractions such as 22/7 and other rational numbers are commonly used to approximate Ï. The digits appear to be randomly distributed; however, to date, no proof of this has been discovered. Also, Ï is a transcendental number â a number that is not the root of any non-zero polynomial having rational coefficients.
