A few facts—did you know the symbol for Pi (π) was first used in 1737 by Swiss mathematician Leonard Euler? And that the value of Pi rounds up to 3.14159? The number is extremely useful when solving geometry problems with circles. The area of any circle equals πr2 where r is the radius or distance across the middle of the circle.
I have no idea what the areas of the circles are on my card, but I know that if I wanted to calculate it out, I could. Sheldon Cooper would say shame on me.
How are you celebrating this March 14? Whether it’s baking your favorite pie, ordering pizza pie, or participating in NASA’s Pi in the Sky challenge, I hope you bring out your inner math nerd today!
