In mathematics, π (Pi, alphabet in Greek script) is the ratio of a circle’s circumference and it’s diameter. It is a constant number which means that for all circles of all sizes the ratio will be the same. It is a irrational number which makes knowing its actual value practically impossible. The value of π is taken as 3.14159265359 for mathematical calculations. Because of its irrationality, it is not possible to represent it perfectly as a fraction. However, 22/7 is the generally accepted fractional representation of π.
