Consider the solid that lies above the square (in the xy-plane) R = [0, 2] X [0, 2], and below the elliptic paraboloid z = 36 m2 2312. (A) Estimate the volume by dividing R into 4 equal squares and choosing the sample points to lie in the lower left hand corners. (B) Estimate the volume by dividing R into 4 equal squares and choosing the sample points to lie in the upper right hand corners. (9_What is the average of the two answers from (A) and (B)
