Any help would be appreciated thank you!
Consider the region in the first quadrant bounded by y = x2 - 1, y = 0, y = 3, and x = 0 which is to be revolved about the y-axis. Sketch and lightly shade the region bounded by the functions above; include a horizontal representative rectangle. Sketch the representative volume element generated by the representative rectangle as the region is revolved about the y-axis. Is it a disk, washer, or shell? Write an expression for DeltaVi, the volume of the representative clement in (D.2). Be sure to use appropriate notation. Write the corresponding Riemann Sum that approximates the volume of the solid of revolution generated by revolving the region about the y-axis. Write and evaluate a definite integral to obtain the exact volume of the solid.
