A bicycle chain fits tightly around two gears.What is the distance between the centers of the gears if the radii of the bigger
and smaller gears are 9.3 inches and 2.4 inches,respectively,and the portion of the chain tangent to the two gears is 26.5 inches long?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

Distance between the centers = sqrt%28%289.2-2.4%29%5E2+%2B+26.5%5E2%29 inches.
