Please answer 2 parts of the question. Thank you

(8%) Problem 10: A physical pendulum consists of a uniform solid disk of radius R supported hanging vertically and supported by a pivot located a distance d from the center of the disk as shown. The disk is displaced a small angle from the vertical and released. Pivot d R A 50% Part (a) Derive an expression for the angular frequency of the resulting simple harmonic motion in terms of the given quantities. 50% Part (b) Calculate a numerical value for the angular frequency if R = 2.35 cm and d = 1.75 cm.
