Sorry, I'd help, but I haven't studied integral volume formulas in aaages. Planning to revisit them soon-ish but not yet.

lgbasallote · Answer

ahh thanks though :) one less from the tagarama will be fun

lgbasallote · Answer

though it might have something to do with the fact that @myininaya is the only person that knows calculus and is on right now

Do you have an example problem?  I'm trying to recall what the process was, but it's not coming to me.  It's been a while since I ever did these types of problems.  lol

lgbasallote · Answer

well there was this one question that dpaInc said could be done with cylindrical shell as well as washer...

Find the volume of the solid obtained by rotating the region bounded by $y = \frac{x^2}{4}$, $x = 2$ and $y = 0$  about the y-axis

What answer did you get for it using the other method?
I may have this yet!  D:

amistre64 · Answer

what is your concept of shells?

lgbasallote · Answer

my concept of shells? like i know $\int_a^b \pi r^2 h dx$ like that?
