Approximate the volume of the solid in the first.octant bounded by the sphere z y? + 22= 64, the planes z= 3. y =3, and the three coordinate planes. To find an approximate value of the double integral, take a partition of the region in the zy plane formed by the lines I 1, I 2, y= 1. and y= 2, and take (Ei, Y) at the center of the ith region. None of the choices. O b. 58.6 cubic units O . 48.6 cubic units O d. 78.6 cubic units O e 68.6 cubic units
