Tomography with few projections

With special classes of objects, it is possible to apply tomographic techniques with only a few projections. Examine the following examples and determine how many projections are required for a complete reconstruction:

1. An arbitrary rotationally symmetric object.

2. An arbitrarily formed object without holes (only one surface) consisting of a homogeneous material.

3. Few small objects that do not superimpose each other in any projection. You only want to determine the center of gravity of these objects and their volume.
