Find the volume of the solid of revolution formed by rotating about the x-axis the region bounded by the curves.I have read textbook but I still don't understand how to solve this problem.

Please help me

F(x)=(3x+2)^1/2, y = 0, x = 1, x = 5

We are given

Formula for the volume when rotated about the x-axis is:

, so

And you can solve from there onwards. - Dec 1st 2008, 09:50 PMMatho

Hi Matho,

I integrated (anti-differentiated) to get , as the formula requires you to do.
