associated with a circle, distribute the basketballs to everyone in the class. While your classmates are playing with
the balls, set up a table with tape, rulers, string, scissors, markers, and any other materials that you think you may
find useful to answer the following questions:
- What is the circumference of the basketball?
- What is the diameter of the basketball?
- What is the radius of the basketball?
- How did you determine these measurements?
- What tools did you use to find your answers?
When playtime is over, use the tools provided to answer all of the above questions. It is the job of you and your
classmates to determine a method of calculating these measurements. For the questions that require numerical
measurements as answers, take 2 measurements for each. You must plot your results for the diameter of the
basketball, so remember to record your data.
