Find the volume of the solid bounded by the cylinder x 2 + y 2 = 16 and the planes y = z, x = 0, z = 0 in the first octant.Find the volume and centroid of the solid E that lies above the cone below and below the sphere X2 + y2 + z2 = 4. Use cylindrical or spherical coordinates, whichever seems more appropriate. .2: 'lx2+y2
