Mr. R.’s World of Math

A pi was discovered,
In ancient Greek times,
Didn’t have apples,

Bananas, or limes…

Unlike desserts,
Those pies people eat,

This pi’s a math constant,
But it’s still really sweet…

Pi’s pretty easy,
It’s 3.14,
It used to confuse me,
But not anymore!
I use it for math,
It’s really quite swell,
Although it’s irrational,
Pi works pretty well…
Areas of circles?

Just try π r 2
It’s the cool constant,
It deserves to be shared…
For circumference you need,
A quick formuli,
Here it is mister,
You gotta’ use pi!

(π⋅d)

Yes, pi’s the cool constant,
Without it I’d cry,
‘Cause I’d fail my math,
If I tried to use pie…
