Cylindrical method formula
WebCylindrical shells do not give the correct "small" surface element because they are all "almost" parallel to the axis of revolution. The correct formula for y = f ( x), a ≤ x ≤ b to find the surface area of the surface formed by revolving f around the x -axis is. S = 2 π ∫ a b f ( x) 1 + ( f ′ ( x)) 2 d x.
