Here’s a fun way to remember the formula for surface area of a cylinder—singing these lyrics set to the tune of Camptown Races (in the style of Foghorn Leghorn):
2 times pi times r times h; that’s the middle.
2 times pi times r times r; top and bottom, too.
Of a cylinder! It’s
2 times pi times r times h plus two times pi times r times r.
If you’re not sure about how to fit the lyrics with the Camptown Races melody, just listen to the intro of this sweet rendition on YouTube:
With this handy mneumonic device stuck in my head, I feel the urge to belt “Surface areAAAA! Of a cylinDERRRR!” while walking around my neighborhood and puttering around my kitchen!
Many thanks to Becky Brickell for sharing this great idea on the Texas Instruments Classroom Activities website!
