Question: If you have a rope around a soccer ball and the moon, which rope would have to increase in length more to create a one meter gap between the rope and the soccer ball/moon?
Hint: Remember, Circumference = Diameter * π
Answer: They would both increase length by 2 π meters. Since Circumference = Diameter * π, when they increase in length it is true that Circumference = (Diameter + 2) * π. Distribute the π and you get Circumference = Diameter * π + 2 * π.
