Question

A coin dealer is having paper wraps made to go around a stack of coins. The coins have a diameter of 12 mm, and the dealer states that the paper should be exactly 36 mm wide, or 3 times the diameter, to go around the coins. Is the coin dealer correct?

Answer 1

No, the coin dealer is not correct. The paper would need to be at least 3.14 times the diameter to go around the coin. The circumference of the coin will be diameter times pi, so 12(3.14).
