Homework Statement
Find the volume generated by rotating the area bounded by y=2+x and y=x^2 about the y-axis.
Homework Equations
Volume of revolution.
The Attempt at a Solution
shell method
integral (0 to 2) of x(2+x-x^2) dx
I think this can be solved by eliminating the left part and only count the volume of the left side, because the left part of the solid result is covered by the right part. It's a problem in my school because our teacher is debating whether the left part is counted or not.
i'm sorry i can't write in equotion.. I'm newbie
