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 (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).n basic mathematics, pi is used to find area and circumference of a circle. Pi is used to find area by multiplying the radius squared times pi, or. So in trying to find the area of a circle with a radius of 3 centimeters, Ï3 2 = 28.27 cm.
