Happy Pi Day

March 14 (3.14) is Pi Day. As we all know, Pi (symbol: \pi) is a mathematical constant which is the ratio of the circumference of any circle to its diameter.  That means that if we measure the circumference of a circle and divide it with its diameter, then the quotient is always \pi. The constant \pi is an irrational number; it starts with 3.14 and continues forever.
