We wrapped up the activity on solid objects today and then spent some time reviewing for the test on Monday. We went over 3-4 problem types that involve using the formulas backwards to find a particular dimension (radius, height, etc.). The students then got to work on the second review sheet for chapter 12 and/or finish up their final measurements for the solid objects activity.
Assignment: Chapter 12 Review Sheet #2
Similar Solids

2. radius = 6; volume = 288 pi
3. radius = 1/2; area = pi
4. 40 pi
5. 512 + 128 pi / 3
6. yes
7. a. 2/3 b. 4/9 c. 8/27
