Question

Here are two students' answers for each question. Do you agree with either of them? Explain or show your reasoning.

How many feet are traveled by a person riding once around the merry-go-round?

⚫ Clare says, "The radius of the merry-go-round is about 4 feet, so the distance around the edge is about 8π feet."
⚫ Andre says, "The diameter of the merry-go-round is about 4 feet, so the distance around the edge is about 4π feet."

Answer 1

they are both correct

Explanation:

If the radius is 4 feet like Clare says, the circumference would be 2(radius)(pi) which is 8pi.

If the diameter were 4 feet, circumference would be (diameter)(pi), which is 4pi.
