D. 432π cm^3

First, we need to find the radius of the sphere, which is half of the diameter, so the radius is 6 cm. The volume of the sphere is (4/3)πr^3 = (4/3)π6^3 = 288π cm^3.

The sphere is enclosed by the cylinder, so they share the same radius. The volume of a cylinder is given by πr^2h, where r is the radius and h is the height. Since the height of the cylinder will be equal to the diameter of the sphere, h = 12 cm.

V_cylinder = π * 6^2 * 12 = 432π cm^3

Therefore, the volume of the cylinder is 432π cm^3.
