Rotational Inertia Practice Test

Two identical uniform solid disks rotate about axes perpendicular to the disks. Disk A rotates about an axis through its center. Disk B rotates about an axis perpendicular to the disk through a point halfway from the center to the rim. Which disk has the greater rotational inertia about its stated axis?

Two uniform rods each have mass $M$ and length $L$ and rotate about axes perpendicular to the rod. Rod A rotates about an axis through a point one-quarter of the length from an end. Rod B rotates about an axis through its center. Which rod has the greater rotational inertia about its axis?
