test-6 - Math Practice Test

A circular tower stands surrounded by a circular moat. A bridge provides a passage over the moat to the tower. The distance from the outer edge of the moat to the center of the tower is 100 meters. The area of the floor of tower is $4900\pi$ $m^{2}$. How long is the bridge over the moat?
