Repeated Reasoning

This seems familiar...

When perfoming a series of related calculations, did you notice...?

...that some numbers were used over and over again? This repeated pattern should help you find the answers quicker by simplifying these calculations.


Find the repetition... What short cuts could you use to find the remaining pieces if the repeated portions are known?

r = Radius
2 r = Diameter
2 pi r = Circumference
2 pi r h = Volume
pi r h = Lateral surface area of cylinder
