 7. Let E be the region in the first quadrant enclosed

7. Let E be the region in the first quadrant enclosed by the line y = ma and the curve y = >. V1 is the volume of the object by rotating the region E about y - axis and V2 is the volume of the object by rotating the region E about x - axis. S1 is the surface area of the object by rotating the region E about y - axis and S2 is the surface area of the object by rotating the region E about x - axis. (a) If m = 1, find the ratio M. (15 points) (b) Find m such that the ratio s, " is the minimum. (15 points)
