9. TRACK A running track has an inner and outer edge. Both the inner and outer edges consist of two semicircles joined by two straight line segments. The straight line segments are \( 100 \) yards long. The radii of the inner edge semicircles are \( 25 \) yards each and the radii of the outer edge semicircles are \( 32 \) yards each. What is the area of the track? Round your answer to the nearest hundredth of a yard.
\( A = \)
