Happy Pi Day!

Happy "Pi Day"!  Not pie the pastry, but pi the number.  


We use pi to figure the circumference and area of circles and the volume of spheres and cylinders.

Written to two decimal points it equals 3.14, like 3/14 or March 14th.

Written to 100 decimal points...

3.14159265358979323846264338327950288419716939937510582097494459230 78164 

I never learned pi past five decimal points.  I only remember it because of a chant that I learned in college.  From 1993 to 1997 I attended the Illinois Institute of Technology.  One of the school chants was:

"Tangent, secant, cosine, sine
i, pi, cube root 3
Rock 'em, sock 'em IIT!"

Go Scarlet Hawks!
