Circumference vs. Diameter Lab

Luis and Jason discovered a relationship between the circumference and diameter of a circle.

In this laboratory investigation, you will investigate the relationship between the circumference and the diameter of circles by measuring precisely. You will measure the circumference and diameter of at least three different-sized circles.
  1. How can you accurately measure the circumference and diameter of a can or a lid? Choose a method to use in the lab.
  1. Draw a picture that shows your experiment. Your picture should show the method you chose to measure the circumference and the diameter. Label the circumference C and the diameter D.
