## Homework Statement

Find the area of the surface generated by revolving the curve y=√x+1, 1≤ x ≤5, about the x-axis.

I'm stuck trying to figure out how I can use substitution...if I am even able. I was trying to rewrite 1 as 4(x+1)/4(x+1) but still can't seem to get the right terms to cancel to allow me to continue further.
