Which expression represents the volume, in cubic units, of the composite figure? ~4, 8, 6, 10

A cylindrical metal pipe has a diameter of 20 millimeters and a height of 21 millimeters. A cylindrical hole cut out of the center has a radius of 6 millimeters. ~20, 21, 6 Which expressions represent the volume of metal needed, in cubic millimeters, to make the pipe? Check all that apply.

Cavalieri's principle states that if two solids of equal height have equal cross-sectional areas at every level parallel to the respective bases, then the two solids have equal volume. The two shaded solids both have a height of 2r units. At every level, the areas of the cross sections of both solids equal π(r2 - b2). Therefore, the formula for the volume of the sphere can be derived by writing an expression that represents the volume of
