Unformatted text preview: y 2 + z 2 = 4 and x 2 + y 2 + z 2 = 9 where the density is the distance to the center of the spheres. VI. Find the mass of the region that is in the ﬁrst octant and also has bounds x 2 + z 2 = 1 and y 2 + z 2 = 1 and the density is the distance to the xy plane. (You can do this with Cartesian coordinates. Which direction do you want to go in ﬁrst?) 1...
