1. The problem statement, all variables and given/known data Find area of surface generated by revolving about x-axis. y=x^3/3 1<=x<=sqrt(7) 2. Relevant equations find f'(x) = x^2 3. The attempt at a solution A = integral[ (x^3/3) * [(1+(x^2)^2] ^(1/2) ] ]dx = integral[ (x^3/3) * [(1+x^4) ^(1/2) ]dx I just don't know where to go from here. Any help is appreciated, Thank You.
