Question
The tendency of a solid to resist a change in rotational motion about an axis is measured
by its moment of inertia about that axis. A solid G with continuous density function
8(x,y, z) has moment of inertia about the z-axis given by
Iz
(x2 + y²)8(x,y,z2)dV
Let G be the solid in the first octant bounded below by the cone 3z? = x? + y?, above by
the sphere x? + y? + z? = 1, and on the sides by the planes x = v3y and x = 0.
If the density at each point P in G is 23 times the distance of P from the z-axis, set up (do
not evaluate) the iterated triple integral in cylindrical coordinates equal to the moment of
inertia of G about the z-axis.
