Set up, but do not evaluate, the integral for finding the surface of the region obtained by rotating the curve y = 3 + 2x³/², 0 ≤ x ≤ 1, ii. about the y-axis.

Find the exact volume of the solid that results when the region bounded in quadrant I by the axes and the lines x=9 and y=5 revolved about the a x-axis b y-axis

For the sphers x-12+y+22+z-42=36 and x2+y2+z2=64, find the ratio of their a surface areas. b volumes.
