Pi Day is Coming

March 14, 2015 is Pi Day. You might be thinking the dessert kind of pie. It’s actually a irrational (never ending) number. Believe it or not, the first three numbers are 3.14. See the connection to the date and the first three numbers? This year it’s even more fun because Pi Day is going to be on 3/14/15 and the first five numbers are 3.1415. If you want to get more accurate you’ll add more numbers; 3.1415926 and so on.Here’s all we know: 3.1415926 5358979323 84626433 8327950 28841971693 9937510582. There’s more, but as we said it’s an irrational number. You’d use pi to find the area of a circle or the volume of a sphere. Pi is the relationship between the circumference and the diameter of a circle.
