The first video explains questions #1 - 13. The 2nd video explains questions #14 - 20. Below is a quick video to complete the rest of the notes we took in class today. Homework is to complete the 12 problems in the packet you received in class today. Homework tonight is to complete your packet on volume for prisms & pyramids. Please refer to the notes we took in class if you need help. Below is a video reviewing cross sections of cylinders, cones and pyramids that we explored today in class using playdough and dental floss. Please watch the video below that explains naming prisms & Cavalieri's Principle. Cavalieri's Principle: if the area of the cross sections (bases) of two solids are the same and the heights are the same, then the volumes are the same.
