Happy Pi Day!

Happy Pi Day!

Pi (π) day is celebrated every March 14th (3.14), which also happens to be Einstein’s Birthday. Here at Aras we’re celebrating with a pie off and pi trivia. How are you celebrating?

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. Here’s what a million digits of pi looks like.

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
