B4 (15 points) The diagram shows the curves y= and y= 1/123x . Let R be the region bounded by these two curves and the x-axis. Answer the following questions. Show and explain your work. (a) Suppose that a solid is obtained by rotating R around the x-axis. Find the volume of this solid. (b) Find the value of k so that if we cut the solid at x =k, we get two parts of equal volume (see diagram). Til Answer the following questions. Show and explain your work.
