Having trouble mostly with number 1, theothers I've pretty much figured out.
MTH 151 - Volumes Using Integrals For each of the following (10 points each) Sketch the graph of the indicated region. The points of intersection of the boundaries of the region are probably self-evident, but pay attention to where they are. (2 points) Expand your graph to show the solid generated by revolving the region about the indicated line. (1 point) Use disks, washers, or shells, as directed, to find an integral for the volume of the solid and include a "sample slab" in your graph. (4 points) Use the first form of the Fundamental Theorem of Calculus to find the volume. Include the antiderivative you use and your substitutions into that antiderivative. (3 points) . o . . 1. The region is bounded by the graphs of y =ç º, x = 1, x = 8, and y = 0, Use disks to 2. The region is bounded by the graphs of y = and y = x2. Use washers to find the 3. The region is bounded by the graphs ofy = find the volume when the region is revolved about the x-axis. volume when the region is revolved about the line y = 1.5 when the region is revolved about the line x =-1. y-x. Use shells to find the volume
