Hi,
Im having trouble solving a really simple integration problem.
R is the finite region bounded by are rotated around the x axis. Determine the volume of the solids.
Okay
The line and the curve interect at Y=0 and Y=4 so these are our upper and lower limits of integration.
But the answer is zero and it's wrong
What am i doing wrong?
I didn't think s/he was... Seems to me we're integrating perpendicular to the axis of revolution... Solid of revolution - Wikipedia, the free encyclopedia

Hello, Jones!
is the region bounded by is rotated about the x axis.
Determine the volume of the solid.Code:| * * | * * | o(3,3) | *::::* | *::::::::o(4,2) | *::::::::* | *:::::::* | *:::::* - - o - - - - - - - - - - - - - - |
Intersection: .
. . The graphs intersect at (0,0) and (3,3).
"Shells" Formula: .
We have: .
Now finish up . . .
