i need some help w/ this problem the region bounded by y=x^3, y=0, x=3. Is rotated about the line x=-1. What is the volume of the resulting solid? help would greatly be appreciated

Hello, bavery25! Did you make a sketch? The region bounded by is rotated about the line What is the volume of the resulting solid? Code: | | * | : | * : | *| : | *::| : | *:::::| - - : - - * - - - - + - - -1 | 3 | Formula: . So we have: .
| | * | : | * : | *| : | *::| : | *:::::| - - : - - * - - - - + - - -1 | 3 |
(1+x) is radius i think and height is (x^3)
oops need to correct it its x=1 not x=3 sry

yea i had that part but my professor has the answer as 7pi/6 and i cant get that so idk what im doing wrong
