The graph of y = (x), for a x b, is rotated about the y-axis.

Question:

The graph of y = ƒ(x), for a ≤ x ≤ b, is rotated about the y-axis. In this situation, the surface area of the resulting surface is

TSX  S = 2 x1 + f'(x) dx

Determine the surface area for each surface of revolution. If the surface area cannot be computed exactly, find an approximate value.

ƒ(x) = ln x, [1, 4]
