Step 1
First, we need to find the intersection points of the given curves y = 9x and y = 0. To do this, we set y = 0 and solve for x: 0 = 9x x = 0 So, the intersection point is (0, 0). Show more…

The volume of the solid obtained by rotating the region bounded by x=9y^2, y=1, x=0, about the y-axis can be computed using the method of disks via an integral V=∫ba ? dy with limits of integration a= and b= . The volume of this solid can also be computed using cylindrical shells via an integral V=∫βα ? dx with limits of integration α= and β= . In either case, the volume is V= cubic units.
Use cylindrical shells to find the volume of the solid obtained by rotating the region bounded by the graphs of y = x, y = 9 - x, and the x-axis about the x-axis.
