Homework Statement
Find the volume of the solid rotated about the given axis
Homework Equations
∫R^2-r^2dx
Disk method
The Attempt at a Solution
I'm having trouble finding the limits of integration: here's my setup
Pi∫(x^3+1)dx and integrated from -1 to 1. I got this by setting y=-1 equal to y=x^3
X^3=-1=-1
Then I get (16/7)pi which I believe is the right answer so can anyone tell me whether my method is correct. I'm using the disk method here.
