How to Celebrate Pi Day

What is Pi?

Pi (π) is the sixteenth letter of the Greek alphabet. It represents the ratio of a circle’s circumference (the length around the circle) to its diameter (the length from one side through the middle to the other side). Regardless of the size of the circle, pi is always the same number. You can find the number pi by dividing a circle’s circumference by its diameter. You should always get 3.14159… or pi.

Why March 14?

Pi is an irrational number that never ends, but the first three digits are 3.14. When writing out March 14 in short form it is 3-14, the first three digits of pi. March 14, 2015, was known as “Epic Pi Day” because it represented the first five digits of pi: 3-14-15.

How to Celebrate Pi Day

Eat Pie – Even though National Pie Day is January 23, we enjoy the excuse to eat pie any chance we get, and Pi Day is cause for celebration. Any holiday that combines math with something as delicious as pie is high on our list. Check our Pie Finder to find Tippin’s pies near you or bake a pie with one of our pinned recipes.

Find the Pi of Pie – A great way to explain pi to someone is with pie. Get a piece of string or yarn and measure around the pie. Then take a ruler and measure the string (circumference). Then measure the length across the pie through the center (diameter). Now divide the circumference by the diameter. You should get 3.14.
