Find the area of the surface obtained by rotating the curve y=1+5x^{2}from x=0 to x=8 about the y-axis

2. Relevant equations

A_{s}=[tex]\int[/tex]2[tex]\pi[/tex]g(x)sqrt(1+[g'(x)]^{2})

3. The attempt at a solution

I changed the limits to suit the y direction, the lower limit becomes 1 and the upper 321. I solved x as a function of y in order to rotate around the y axis and when I plug everything into the formula is becoems a really messy integral I can't solve. I'm sure there's an easier way.
