All circles are similar to each other.
In any similar figures, the ratio of areas is the square of the ratio of lengths, and the ratio of volumes is the cube of the ratio of lengths.
In this problem, since the ratio of areas is 100:1, the ratio of any lengths, including the circumferences, is 10:1.
