Given the surfaces: S1: (x- 1)' + (y - 1)2 =1, $2:x2 =y, 53 : x2 = -(2 -1) S : x+z=1, Ss :x=0, 56 :y=0 y S7 : z=0. Consider the solid Q shown below (two views of the same solid are shown) which is generated, in the first octant, by some of the above surfaces: The curve C shown in the drawing is obtained as the intersection of the surfaces: A) Sly SA B) S y Ss C) S2 y SA D) Say SA
