Please answer the following questions using Matlab! Thank you !

1. Consider the region bounded by the functions f(x) = ln(x) + 2 and g(x) = 2 ln(x^2 + 1).

(a) Plot the graphs of these functions in the same plot on the interval [0, 2].

(b) Find the volume of the solid whose base is the region bounded by these curves and whose cross sections perpendicular to the x-axis are semicircles.
