Let f and g be the functions given by f(x)=e^x and g(x)=ln x.

b) Find the volume of the solid generated when the enclosed region of f and g between x = Â½ and x = 1, is revolved about the line y = 4.

c) Let h be the function given by h(x)=f(x) - g(x). Find the absolute minimum value of h(x) on the closed interval Â½ &#8804;x&#8804;1, and find the absolute maximum value of h(x) on the closed interval Â½ &#8804;x&#8804;1. Show analysis that leads to your answers.
