washer method!?

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

  • Calculus -

    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

  • Calculus -

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

    your right im sorry, i was thinking we were rotating around x=3 lol but will you do it so i can check my answer?

    I got 32pi/5

    i think u forgot to add the 2x^3 to the antiderivitive for the fundamental theorm step
