Homework Help: HELP:Volume generated( shell )

    HELP:Volume generated("shell")

    Find the volume generated when the region bounded by the graph of
    f(x) = 4x^2
    and the graph of
    H(x) = 4
    is rotated around the line y = -1

    How do I solve this? How do I know if, when rotated, if the solid form a "shell" or a disc, or a washer?

    Use Pappus' Theorem to find the volumes for each function then compute the difference.
