[9] (a) and (b) Set-up and solve the definite integral to find the surface area when the curve is revolved about each of the coordinate axes. After you get an exact answer give a decimal approximation to the nearest hundredth. Use definite integrals to represent the areas of the surfaces generated when the curve y = 2 + x ,0sx< 3, is rotated about each axis.
