Let B be the solid bounded by the surfaces z=3x^2+4y^2,   x^2+y^2=25, and the xy-plane (distances in cm). Suppose B has a constant mass density of 4 g/cm^3. Here, you will compute the moment of inertia of B about the axis through (−3,4,−4) that is perpendicular to the yz-plane. (a) What is the square of the distance between an arbitrary point (x,y,z) and the axis? r^2=  (b) Find the moment of inertia of B about the axis. Include units on your answer. I=
