Slice of PI

"Imagination is more important than knowledge. For knowledge is limited to all we now know and understand, while imagination embraces the entire world, and all there ever will be to know and understand."
— Albert Einstein

"PI Day is celebrated on March 14th (3/14) around the world. PI (the Greek letter π) is the symbol used in mathmatics to represent a constant — the ratio of the circumference of a circle to its diameter — which is approximately 3.14159."

Lyrics:

There are radians and there are degrees
And their conversion can be done with ease
Look at a circle - sketch one on a pad
One revolution equals 2π rad

How do you measure a slice of PI?
Do you know how and why?
Angles, diameter, and radii
Lots of math to apply

Take any angle and divide it by
One hundred eighty, then multiply by PI
Now take this process - do it in reverse
There's nothing simpler in the universe!
