Best Answer

Pi is a Greek letter. It is used in mathematics to represent the number 3.1416.

One may calculate the circumference of a circle by multiplying the diameter by pi. One may calculate the area of a circle by multiplying the square of the radius by pi.

Pi is actually a little less than 3.1416, but that's close enough for most applications.
