pi (math)

ฯ€

A number represented by the ๐œ‹ symbol. It is the ratio of a circle's circumference to its diameter, roughly equal to 3.14159 (this number is infinite and non-repeating, or an irrational number). This means that a circle's circumference (the entire circle itself) is a little more than three times as long as its diameter (a straight line running through the circle).
