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 name given to the ratio of the circumference of a circle to the diameter. That means, for any circle, you can divide the circumference (the distance around the circle) by the diameter and always get exactly the same number. It doesn't matter how big or small the circle is, Pi remains the same. Pi is often written using the symbol and is pronounced pie, just like the dessert.
