# 5.6: Solve Circle Problems by Working Backwards

## Section 5.6: Solving Circle Problems by Working Backwards

This is the final section of Chapter 5: Measurement of Circles. This section introduces students to complex problems, where they have to work backwards to find the radius or diameter of a circle, and then use that knowledge to complete the problem.

We took a few classes to work through four support questions together, exploring the nuances of each.

## Support Questions

Students identified what they felt were the most important questions to solve. The following questions are due on Tuesday, October 6th:

- p. 170-71, #5, 6, 9, 11, 12
- p. 173, #2, 5, 7, 8 (Interesting, but optional: #4, 6, 11)
- p. 175, #6, 9(Interesting, but optional: #4, 8)
