Chapter 8.3, Problem 40E

What is the volume of the solid below? (1, 1) y=x y=x (0, 0)

Find the volumes of the solids Find the volume of the solid generated by revolving the regionbounded by the x-axis, the curve y = 3x4, and the lines x = 1and x = -1 about the x-axis

Use the disk method or the shell method to find the volume of the solid generated by revolving the region bounded by the graphs of the equations about each given line. y = 6/(x2),  y = 0,  x = 1,  x = 3 (a) the x-axis (b) the y-axis (c) the line y = 6
