The mass of the solid inside the sphere: x^2+y^2+z^2=1, above the xy plane and below the cone z=SqRT(x^2 + y^2. It's mass density is equal to the square of a distance from the origin, setup in both spherical and cylindrical coordinates. I don't have to evaluate, but i still can't get this problem right(either coordinates)
