Happy Pi Day 3.14 – Quizzes & Resources

Happy Pi Day! To celebrate this irrational day, we have provided a few quizzes for your constant enjoyment. Of course, they are heavy on pi. (That is, π).

Pi Day celebrates the mathematical constant (π), as March 14 can also be expressed as 3.14, the first three digits of pi. Pi is the ratio of a circle’s circumference to its diameter, which is a constant. That is – for any size circle, the ratio is the same (π).

Happy Pi Day

 

The first large-scale celebration of Pi Day was organized by Larry Shaw at the San Francisco Exploratorium, where Shaw worked as a physicist. Then in March 2009, Pi Day became a national holiday in the United States. And a fun note? March 14th is also Albert Einstein’s birthday. Don’t worry, unlike Pi, this history lesson won’t go on forever. Onto the math!
