Chapter 7 Test February 4, 2003 No Calculators Name Diagrams are recommended but not required. 1. Find the area of the region bounded by the graphs of the equations x y 3 and y x ² 2 and y 2. 2. Find the volume of the solid generated by revolving the region bounded by y 1 ³³³³ 2 x ² 1, y x ² 1, and x 3 about the y ± axis. 3. Find the volume of the solid generated by revolving the region bounded by the graphs of the equations y x , y x 2 ² 2, and x & 0 ² in the first quadrant ³ about the x ± axis. 4. A solid has as its base the region in the xy ± plane determined by the graphs of the equations x y 2 ² 4 and x 0. Every cross ± section by a plane perpendicular to the y ± axis is a triangle with base equal to height. Find the volume of the solid.

The plate is submerged in water so that the shortest base is parallel to, and closest to, the surface of the water, at a distance of 5 feet. Find the force exerted on one side of the plate. 8. A force of 12 lbs is required to stretch a spring from its natural length of 5 inches to a length of 8 inches. Find the work done in stretching the spring from a length of 9 inches to a length of 16 inches. 9. Find the volume of the solid generated by revolving the region bounded by y & ± x 2 ² 2 x and y & ± x about the line x & ± 2. 10.
