Pi (Ï), the 16th letter of the Greek alphabet, is used to represent the most widely known mathematical constant. By definition, pi is the ratio of the circumference of a circle to its diameter. In other words, pi equals the circumference divided by the diameter (Ï = c/d). Conversely, the circumference is equal to pi times the diameter (c = Ïd).
