2. A man places his lawn sprinklers at the vertices of a triangle that hassides of 9 ft, 10 ft, and 11 ft, respectively. The patterns of the watersprinklers are circular with radii of 4 ft, 5 ft, and 6 ft, and no area iswatered by more than one sprinkler. Calculate the amount of area insidethe triangle that is not watered by any of the three sprinklers, State theanswer to the nearest thousandth of square feet.3. During the heat of the day, the 100-foot bridge expands 1 inch. Now, theends of the bridge are embedded in rock, and the bridge buckles upwardand forms an arc of a circle for which the original bridge is a chord.Determine the approximate distance moved by the center of the bridge.
