Happy “Pi” Day?
So, today everyone has been referencing some “Pi Day”. Upon further investigation, I realized the reference is in regard to today’s date: 3/14. Clever…sort of. Pi (Π), often rounded off to 3.14, is actually a mathematical constant used to calculate the area of a circle (A= Π r²). It is a never-ending number. The first 100 digits look like this:
3.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679
Scary, eh? If you’re still confused or would like to learn more about Π, you can check out the following items found online in EDUCAT, the TC Catalog:
