March 2021 - What's Happening @ LWLC: National Pi Day

National Pi Day

March 14 when written as 3.14 in date notation looks the mathematical constant pi (π), the ratio of a circle's circumference (distance around the edge of a circle) to its diameter (straight line across a circle through its center).

Due to this similarity, the U.S. House of Representatives in 2009 passed a resolution declaring March 14 "National Pi Day". The first celebrations were held in 1988.
