What is Pi?
Pi is the sixteenth letter of the Greek Alphabet that 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 (doesn’t matter the size) circumference by its diameter. You should always get 3.14159…or pi.
Why March 14?
Pi is an irrational number and 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 Epic Pi Day because it was the first five digits of pi: 3-14-15.
How to Celebrate:
Eat Pie – Even though National Pie Day is January 23, we like the excuse to eat pie any chance we get! Check out our pie finder to find a Tippin’s pie near you, ship yourself or a friend a Tippin’s pie, 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!
Celebrate with us at Science City – We love getting involved to help better the community. This year, we will be at Science City measuring and eating pies. Join us at Union Station on March 14 to celebrate Pi Day!
