(11) Find the volume of the solid formed by rating the region bounded by y = $12,113 = 2, :0 = 2 and the x-axis around the altaxis. (12) Set up, but do not evaluate, the integral to nd the arc length of the curve y = a: on x = [0, 1]. (13) Set up, but do not evaluate, the integral to nd the arc length of the curve y = %(:c2 + 2)3/2 from x = 0 to :6 = 1. 3/2
