(a) Evaluate JE DV, where E is the solid enclosed by the ellipsoid x²/a²+ y²/b ² + z²/c² = 1. Use the transformation x = au, y = bv, z = cw. (b) The earth is not a perfect sphere; rotation has resulted in flattening at the poles. So the shape can be approximated by an ellipsoid with a = b = 6378 km and c - 6356 km. Use part (a) to estimate the volume of the earth. (c) If the solid of part (a) has constant density k, find its moment of inertia about the z- axis.
