We went through another entry task today practicing the use of our various formulas. We then spent some time taking a look at some animations of how cones are constructed from triangles and how they are related to cylinders. The class got some new formulas for how to work with cones and then did a couple of sample problems together before getting started on the homework.
Quiz on volume and surface area of solid objects tomorrow.
Assignment: section 12-3; page 493; #9-16 all, 18
