Homework Statement
y=x^(1/2) x=4
find volume of revolution about the line x=4
this was a test problem and i chose x as p(x) [radius] but now i think that it should've been (x+4).

I'm confused too !en bloc said:Homework Statement

Yes, of course! I get that, but what did you mean byen bloc said:In calculus II, graphing a function and then revolving it around an axis. calculate that volume either by disk/washer method or shell method.
and the formula for the shell method is
2\pi \int_{a}^{b} (p(y)h(y))\,dy

You need at least one more boundary; perhaps the x-axis ?en bloc said:it's the region bounded by y = \sqrt{}x and x = 4
