# Green Flame Vortex for Pi Day and St. Patty’s Day!

March 14 is Pi Day and to celebrate I’ll be creating some unique St. Patty’s Green Pi Pies using science so that we can calculate Pi!

Try this:

Celebrate Pi Day by making different size pies and then calculate the value of Pi.

To calculate the value of Pi determine the circumference of a circle by taking a string and wrap it around the circle of your pie and measure the length of the string with a ruler.

Then measure the diameter of the circle of your pie:

Pi is the circumference divided by the diameter.  Using a calculator calculate the value of Pi of your Pie.

Repeat with as many pies as you want!  Eat and enjoy your new discovered Pi!

Explanation:

In mathematics Pi (symbol p) is an irrational number and one of the most well-known mathematical numbers.  It is calculated by taking the circumference of a circle divided by its diameter.  The calculated value of Pi goes on forever in a random sequence.  The value of Pi starts off at 3.141559… and thus the reason Pi Day is celebrated on March 14!

Pi has been recited by memory to 100,000 digits by a man named Akira Haraguchi a retired Engineer from Japan.  By computer Pi has been calculated to 10 trillion digits.
