Using the disk method, determine the volume of a solid formed by revolving the region bounded above by the line y = 9, on the left by the line z = 0, and below by the curve the x = y about the line y = 9. The 2d picture below may help in determining the radius of the disk used in setting up the integral for the volume. y=a + 2= yi Setup the integral that represents the volume of the solid of revolution described above.. Part 2. The volume of the solid is units cubed.
