washer method!?

Find the volume of y=x^2+3, y=3, between [0,2] around y=3

    make a sketch

    wouldn't your volume be the same if you rotated y = x^2 around the x-axis, for [0,2] ??

    I am sure you can do that easy one.
    let me know what you got.

    No it wouldnt be the same because one is a disk rule one is a washer rule

    you are rotating it around y=3, so there is no hole.
