Question

Find the volume of the solid obtained by rotating the region bounded by the given curves about the specified axis.
y=1+1/x^3, y=1, x=4, x=7;
about the x-axis

Answer 1

So I set up my integral like this:

\[A = \pi \int\limits_{4}^{7} [(1+1/x^3)^2) - 1^2]\] and evaluated it but it wasn't correct :(
