This is another video in the series looking at Using Units of Measurement and Measurement and Geometry. Building on the previous videos where we have been looking at finding the surface area for basic shapes (which then build into compound shapes), I now look finding the surface area of one of the most interesting shapes in Mathematics - the cylinder. With a practical demonstration of how the surface area is found, I look at the formula and how it is constructed. There are lots of worked examples which are explained using easy to understand (and humourous) theory.
