Find the exact area of the surface obtained by rotating the curve about the x-axis. 9x=y2+36, 45x58 Ex iEnhanced Feedback EPlease try again. Remember that the formula for the surface area of the surface obtained by rotating the curve 3/ = f(x), as x s b, b Eabout the x-axis is S = / 21rf(x)\\/ 1 + [poof dX. Find y as a function explicitly defined in terms of x, then use the arc length .3 Need Help
