NOTE: PLEASE ANSWER THE LAST THREE SUBPARTS. Activity:ed2.3. C4. Compute the area of the surface formed when f(r) 2+ cosh(z) between 0 and 1 is rotatedaround the x-axis.5. Consider the surface obtained by rotating the graph of f(z) 1/2, z 21, around the z-axis.This surface is called Gabriel's horn or Toricelli's trumpet. In exercise 13 in section 9.7we saw that Gabriel's horn has finite volume. Show that Gabricl's hern has infinite surfacearea,6. Consider the circle (r-2) + y 1. Sket ch the surface obtained by rotat ing this circieabout the g-axis. (The surface is called a torus.) What is the surface area? >
