Estimate the volume of the following solids by Riemann sums n v~f(x,y;) i=1 i 1 I m Estimate the volume of the solid above the rectangle R=[0.2]x[-1.1] and below the elliptic paraboloid To do this, divide the rectangle R into 16 subrectangles and choose the point to be evaluated as the upper right corner of each partial domain. 2 = 16- x - 2y.
