Basic Disk VS Dynamic Disk (The Features, Differences, and Conversion)

Solid of revolution between two functions (leading up to the washer method)

Two disks are rotating about the same axis. Disk A has a momentof inertia of 3.2 kg · m2 and an angular velocity of 6.8 rad/s.Disk B is rotating with an angular velocity of -9.1 rad/s. The twodisks are then linked together without the aid of any externaltorques, so that they rotate as a single unit with an angularvelocity of -2.6 rad/s. The axis of rotation for this unit is thesame as that for the separate disks. What is the moment of inertiaof disk B?
