The height of a sphere is twice the radius, in other words, the diameter. So the object described in the question suggests two different radii, one 3.5 and the other 4. This is an oblate spheroid, a squashed or distended sphere. The volume of such an object is (4/3)(pi)a^2b, where a is one radius and b the other. Therefore the volume is (4/3)(pi)3.5^2*4 or (4/3)(pi)4^2*3.5, or 205.25 or 234.57, depending on whether a sphere of radius 4 has been squashed or a sphere of radius 3.5 has been distended or stretched.
