Week 11:

Due Tuesday, March 30: Read section 9.6 and do the exercises (we will, at least for now, skip over 9.5). Hand in problem 2 on page 205, problem 8 on page 207, and the following additional problem: Suppose that you have a map with a scale of 1 inch = 100 miles. You trace a state on the map onto 1/4 inch graph paper (the grid lines are spaced 1/4 inch apart). You count that the state takes up about 80 squares of graph paper. Approximately what is the area of the state? Explain.

Due Thursday, April 2: Read section 9.7 and do the exercises. Hand in problem 4 on page 235 and problem 5 on page 238. For problem 5, explain how to use Figure 9.76 and the moving and combining principles to show that the area of the shaded triangle is 1/2 b times h for the given choices of b and h.

Week 12:

Due Tuesday, April 6: Study for the quiz. The quiz will consist of problems similar to the ones on the following lists: section 9.1 - 9.3 problems and section 9.4 - problems, problems 1 - 4 only.

Due Thursday, April 8: Read sections 9.8 and 9.9 and do the exercises. Hand in: problem 1 on pages 242, 243, except that you may explain the formula for the area of a trapezoid in a way other than using Cavalieri's Principle if you like, also hand in problem 2 on page 251, 252.
