Mr. R.’s World of Math

I’m rolling and rolling,
3-60 degrees,
Going in circles,
Rolling with ease…
   
I go all around,
No start, and no end,
Will roll on a line,
Will roll on a bend…
Circumference, around me,
You’ll never get lost,
The shape of the moon,

Or ball for lacrosse…

Diameter, twice my radii,
To find my area
You gotta use Pi…

Cool as a circle,
Don’t fool around,
Got somewhere to go,
Covering ground…
Yeah, I’m a circle,
3-60 degrees,
Rolling in circles,
Rolling with ease…
