# Pi Song (mathematical pi)

A song I wrote for my students for their pi day celebration! I'd say they're irrational,
If their thinking's mathematical,
They'll know the magic's with the constant,
3.14
(Did you say 3.14?)
That's what I said,
Pi's the coolest constant,
24-7 satisfaction,
22/7th as a fraction,
Say pi's the coolest constant,
A non-repeating decimal,
Pi's the magic irrational...
Archimedes tried to solve it,
A Greek dude, a real smart guy,
Searched for ratios in parts of circles,
He tried to pin down pi!
ENIAC, determined more decimals, (actually 2037 digits)
Now there's millions in the mix,
I guess computing's a little quicker than it was in, 1946...
Some people say,
3's the magic number,
But that's not gonna' roll here anymore...
I'd say they're irrational,
If their thinking's mathematical,
They'll know the magic's with the constant,
3.14
(ratio of circumference to diameter)
That's why I think,
Pi's the coolest constant,
24-7 satisfaction,
22/7th as a fraction,
Say pi's the coolest constant,
A non-repeating decimal,
Pi's the magic irrational...
Circumference of all circles,
Like round wheels on a car,
To find how far those wheels have rolled,
Just use 2πR!
The ratio of circumference,
To diameter's straight-straight line,
Pi pinpoints that ratio,
3.14...it's pi time!
That's why I say,
Pi's the coolest constant,
24-7 satisfaction,
22/7th as a fraction,
Say pi's the coolest constant,
A non-repeating decimal,
Pi's the magic irrational...
Area of a circle,
How much is there inside?
That's πr(squared),
Every time,
You find it using pi...
You gotta know the radius,
More than one's the radii,
If you want to use the cool math constant,
3.14 π
Some people say,
3's the magic number,
But that's not gonna' roll here anymore...
