Today Andrew and I began by reviewing some of the SAT problems he had for practice while I was gone. We discussed similarity, properties of parallelograms, and vertical angle theorem. Then we moved back into our Geometry content on Volume. We discussed how volume represents the amount of space on the inside of a 3D figure. We started with cylinder and derived its formula. Andrew recognized the top is a circle so the formula is Pi*r^2. Then we discussed that the volume would then be the area of a circle times its height. I showed him how it doesn't matter if the base is a circle, triangle, square, etc. The formula for the volume will always be the area of the base times its height.
