Question 6: Find the center of gravity of the body bounded (limited) from above by the surface z = square root of 2, from below by the xy-plane and which lies within the cylinder r = 4. The surfaces are given in cylindrical coordinates. The density is 8 = 1 (a) (0,0,1) (b) (0,0, 572). 12 (c)(0,0,8) (d) (0,0
