Find the Mass of That Portion of the Solid Bounded $x ^ { 2 } + y ^ { 2 } + z ^ { 2 } = 3$

Short Answer

Find the mass of that portion of the solid bounded above by the sphere $x ^ { 2 } + y ^ { 2 } + z ^ { 2 } = 3$ which lies in the first octant, if the density varies as the distance from the center of the sphere.
