Parallel-Axis Theorem for an Area

Parallel-Axis Theorem for an Area inertia about the noncentroidal y axis, i v, is the moment of inertia about the centroidal y axis, dz is the perpendicular distance in the x direction between the -centroid and the y axis, Jo is the polar moment of inertia about some noncentroidal point, J C is the polar moment of inertia about the centroid, and d is the distance between the points O and C. Figure Review try myarn; o remerrnrrg 01 c x' Part C The semicircle shown (Eigure 3) has a moment of inertia about the x axis of 90.0 ft' and a moment of inertia about the y axis of 90.0 ft 4 . What is the polar moment of inertia about point C (the centroid)? Express your answer numerically in biquadratic feet (feet to the fourth powerj to three significant figures.
