11.5 Areas of Similar Figures – We practiced finding areas of similar figures by using scale factors. Then we found the scale factors or missing measures given the areas of similar figures. We learned that architecture firms often hire model makers to make scale models and projects that are used to sell their designs. Since the base of a model is geometrically similar to the base of the actual building it represents, their areas are related.
12-2 Surface Areas of Prisms and Cylinders – We practiced finding the lateral areas and surface areas of prisms.
