Calculus Applications of Integration Page 20 Third idea: Consider the solids we have been working with up to this point. Suppose we sliced the solid and pulled out a cross section – what would it look like? Look at the volume formula – how could this formula be viewed in terms of the cross-sectional area Consider another type of solid. This solid is not formed by rotation of a region about a line. Considering a region as its base, then describing its cross-sectional
