LYRICS
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
(Did you say 3.14?)
That’s what I said,
Pi’s the coolest constant,
247 satisfaction,
22/7th as a fraction,
Say pi’s the coolest constant,
A nonrepeating 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,
247 satisfaction,
22/7th as a fraction,
Say pi’s the coolest constant,
A nonrepeating 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 straightstraight line,
Pi pinpoints that ratio,
3.14...it’s pi time!
That’s why I say,
Pi’s the coolest constant,
247 satisfaction,
22/7th as a fraction,
Say pi’s the coolest constant,
A nonrepeating decimal,
Pi’s the magic irrational...
Area of a circle,
How much is there inside?
That’s πr^{2},
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...
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,
247 satisfaction,
22/7th as a fraction,
Say pi’s the coolest constant,
A nonrepeating decimal,
Pi’s the magic irrational...
