Size could mean the circumference (the length of the perimeter) or the enclosed area of the circles. Suppose we finally come to an agreement that by "size" we mean the circumference of the circle. You might state your objective as follows: In this experiment we will determine how the circumference of a circle depends on its diameter.

Circle A has circumference 2 2/3 m. Circle B has a diameter that is 1 1/2 times as long as Circle A’s diameter. What is the circumference of Circle B? Solution. 4 m. If the diameter of Circle B is 112 times larger than Circle A, its circumference must be as well. We can rewrite to calculate: (8/3)(3/2)=4. Problem 5 (from Unit 3, Lesson 2)

2. Students will use a ruler to measure the length of the diameter of each circle, and use a ruler and string to measure the circumference of each circle. Students will use the List function on the TI-83 plus to record data in . small groups. Students will then create a new "Ratio" list by dividing the circumference list by the diameter list. 5.
