<span>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).</span>

No, not enough paper.

Should be 3.14 instead of 3.

The circumference will be 12 times pi.

(12)(3.14) = 37.68
