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.

• Calculus -

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?

• Calculus -

I got 32pi/5

• Calculus -

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