ok i think what's tripping me is the fact that i don't have any x or a function to work with. I have a graph and that's it...how can i make an integral using just that.

amistre64 · Answer

well, do you want to work shells or washers?  or some polar integration?

math2400 · Answer

my goal is to find the volume. I'm fine with working with shells or washers but i prefer washers. Doesn't matter either way haha

how we orientate it is immaterial, as long as our spin and object remain the same, placement is irrelevant so make it simpler for you.  spose we wanted to do shells
