A 106g Frisbee is 18cm in diameter and has half its mass spread uniformly n the disk and the other half concentrated in the rim.

a) What is the Frisbee's rotational inertia?

final answer must be in kg*m^2

b) With a quarter-turn flick of the wrist, a student sets the Frisbee rotating at 620 rpm. What is the magnitude of the torque, assumed constant, that the student applies?

final answer must be in N*m i would greatly appreciate if you showed all your work
