    Volumes rotated about the x-axis.

    So, we just started going over this topic in math and I'm having some trouble with this problem. Any help would be appreciated.

    "In Exercises 1-10, the region is rotated about the x-axis. Find the volume.

    1. Bounded by y=x^2, y=0, x=0, x=1."

    Could somebody get me started please?

    Thank you.

    sketch the graph. this is a straight forward application of the disk method.

    V = \pi \int_a^b [r(x)]^2 \, dx
