Compute the integral, if possible. Use proper notation in your work.Is it possible for a 3D figure to have an infinite surface area but finite volume?' Gabriel's horn can be created by rotating the graph of the function /(x) = _ over the interval [1, co) about the r-axis. a. Graph the region and determine the volume of the solid generated by rotating the graph of /(x) = = over the interval [1, co) about the r-axis. b. Find the surface area of the solid generated in part(a). Hint: To facilitate the integration, use the fact that \\/1+ - 4 > I for all real values of r
