2. (10 points) For the following integral, change the order of integration: J.J. J."f(x, y,z)dxdyaz = [ [,[ f(x,y,z) dy dz dx3. (20 points) Let Wbe the region inside the hemisphere of radius 2, centered at the origin, with z 2 0, and outside the cylinder x2 + y =1. The density at a point in Wis given by f (x, y, z) = Z Vxty 2 + 22 127 :0.8- Set up (but do not compute) integrals to find the mass of W using: (a) cylindrical coordinates. (b) spherical coordinates
