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
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]
