Pi (π) day is celebrated every March 14th (3.14), which also happens to be Einstein’s Birthday. Here at Aras, we celebrated with a pie off and pi trivia. And let me tell you, the pies were delicious! How are you celebrating?

Pi Facts:

Pi is approximately 3.14159 but it never ends and never becomes a permanent repeating pattern.  Pi has been calculated to over 10 trillion digits but most applications require no more than 40 digits.

Pi is most frequently used in geometry, representing the ratio of a circle’s circumference (C) to its diameter (d). π = C/d

Here are a couple examples of formulas involving π:

Area of a circle:  A = π 2

Volume of a cylinder: V = π r 2h
