3) The solid S obtained by rotating the region below the graph of y = x about the x-axis for 1 < x < ∞ is called Gabriel's Horn (Figure 11). y =x- FIGURE 11 (a) Use the Disk Method (Section 6.3) to compute the volume of S. (Note that the volume is finite even though S is an infinite region.) (b) It can be shown that the surface area of S is A = 2T V1+ x dx 1 Show that A is infinite. (If S were a container, you could fill its interior with a finite amount of paint, but you could not paint its surface with a finite amount of paint.)
