Happy Pi Day!

Posted by TJ Easter II on Thursday, March 14. 2024

March 14th is Pi Day (3/14). For those not in the know, pi is a mathematical constant representing the relationship between the diameter of a circle and it's circumference. Pi is also a never-ending number - there is literally an infinite number of digits after the decimal point. For most calculations, only the first 2 digits after the decimal point are necessary. NASA only uses four or five digits after the decimal for their calculations.

For instance, a circle with a 6" diameter would have a 18.8495556 inch circumference.

pi = 3.1415926
diameter = circumference / pi
circumference = diameter * pi
