Problems 1-3
There are many problems throughout the text labeled IN YOUR OWN WORDS. Just relax. Do not be afraid to give your opinion. For the most part, these questions do not have "right" or "wrong" answers. You should spend about five minutes in answering each of these questions.

Problem 4
This question is asking for formulas that you should know.

Problems 5-14
These are estimation problems. Do not answer these questions by doing any direct measuring.

Problems 15-25
See Example 2.

Problems 26-31
See Example 3.

Problems 32-43
See Example 1; remember you are measuring the distance around each figure. In some cases you can combine known formulas. For example, in Problem 35 think of the two ends as semicircles. Use the circumference of a circle formula to find the distance around the ends, then add this number to the lengths of the top and bottom.

Problems 44-53
See Example 4.
