For #3 - #6, suppose that T is a planar lamina, having uniform (constant) density 8. 3. Determine the center of mass of T by setting up and evaluating iterated integrals. 4. Determine the moment of inertia of T about the x-axis by setting up and evaluating an iterated integral. 5. Determine the moment of inertia of T about the y-axis by setting up and evaluating an iterated integral. 6. Use your results in #4 and #5 to determine the moment of inertia of T about the z-axis (i.e., the origin in xy-plane).
