A circular object with a mass of 19.6 kg and radius (outer) of 0.7 meters rolls without slipping down a 39.4 degree incline. At the top of the incline its center of mass is moving at 6.5 m/s and at the bottom of the incline it is spinning at 27.3 rad/s. If the object makes 10.5 revolutions as it rolls down the incline, what is its moment of inertia about its center in kg m2?
