Set up an equation to find the volume of the solid generated when the enclosed area between y = lnx + 4 and y = e^x is revolved about the y-axis

Question

anonymous · Answer

hmm is this a calculus problem?

anonymous · Answer

yeah :(

anonymous · Answer

which calc? 1,2,3?

anonymous · Answer

calc I

anonymous · Answer

it's like the area, volume (disks, washers, etc. ) unit

anonymous · Answer

lol. surprisingly, i know how to do this using calc 3, but not really calc 1... let me think though

anonymous · Answer

haha that's okay, whatever works! thanks (:

anonymous · Answer

wait, so you can't do double integrals right?

anonymous · Answer

no :(

anonymous · Answer

dang... i dont know how to do this without double integrals :(... lol if you want the double integral way: all you do is SS y dydx with limits of y being lnx+4 and e^x and limits on x being the solutions to lnx+4-e^x=0

anonymous · Answer

and times that by 360

anonymous · Answer

sorry

anonymous · Answer

ahh that sounds so much easier, I wish I could do that! D: but thanks for your help!
