Jerry wants to design a gold chain 60 cm long made of thin gold wire circles, each of which is the same size. He wants to use the least amount of wire and wonders what the radius of each circle should be.
a. Each member of the group should choose a specific choose a specific number of circles and find the length of wire needed to make a 60-cm chain with the chosen number of circles.
b. Compare your results and make a conjecture based on the results.
c. Justify your conjecture.
