Consider a lamina occupying the region R and having the density function $\rho$ given in the first two groups of Exercises. a. Find the moments of inertia $I_x, I_y$, and $I_0$ about the x-axis, y-axis, and origin, respectively. b. Find the radii of gyration with respect to the x-axis, y-axis, and origin, respectively. R is the rectangular region with vertices (0, 0), (0, 3), (6, 3), and (6, 0); $\rho(x, y)=\sqrt{x y}$.
