The plate has a hole in its center. (Figure 1) Its thickness is \( 25 \mathrm{~mm} \), Part A and the material has a density of \( \rho=50 \mathrm{~kg} / \mathrm{m}^{3} \). Determine the moment of inertia of the thin plate about an axis perpendicular to the page and passing through the pin at \( O \). Express your answer to three significant figures and include the appropriate units.
