Happy Pi Day!

Pi day is March 14.
3.14
Pi  

Would you share some Pi with me?  =)

Pi (3.14) is used to find the circumference or area of a circle.
Pie is round, like a circle, but Pi are square.  πr² 
To find the area of a circle, use πr² (3.14 x radius x radius).
To find the circumference of a circle, use πd (3.14 x diameter).

The original recipe for Pi is 22/7, and no one has ever found the last digit of pi.  So it is an irrational number.
But an extremely smart person might be alleged to have discovered the last digit of Pi!  =)

Here is just a small slice of Pi.

But that's not the whole Pi!

Here's the history of making Pi.

Don't worry, there is plenty of yummy Pi to go around.
No one has ever gotten the last slice yet.  =D
