I need help solving the following problem. Could someone please help me and explain how to work the equation. Thanks in advance. [intergral x sqrt3x dx I hope this makes sense

use the method of cylindrical shells to find the volume generated by rotation the region bounded by x=y^2+1, x=2, about y=-2. Sketch the region, the solid, and a typical shell. I know that for shells, its 2pix*f(x)*dx. i am having trouble figuring out wha...

Find the volume of the solid obtained by rotating the region bounded by y=x^2, y=sqrt(x), about y=1. I have to use either the disk or washer method and i believe i use washer. i set up the integral to be pi[(1-x^3)^2 -(1-sqrt(x))^2] from 0 to 1 for my lim...

I worked it out and found the answer to be 454pi/12. this is correct right? The limits of integration i used were from 1 to 2.
