A physical pendulum consists of a uniform sphere with radius r=2.5cm and mass M = 0.5kg attached to a uniform rod with length L = 1m and mass m=250g

The friction of the suspension and air moderately reduce the amplitude of oscillation by factor of 2 in 19.6s. What is the damping constant b? Let's assume that the period of oscillation does not change during this time.

I found the moment of inertia to be 0.609 and the center of mass from the pivot point is 0.85m. I'm stuck here
