I can visualize the beach ball, and can imagine the sections being defined as the interiors bounded by vertically oriented planes that contain the straight line between the north and south pole of the beach ball.
So then the cylinder models the human body? With, for example, the longitudinal axis lying in the plane that contains the beach ball's equator? No wait. If the cylinder is the body, then it is oriented the other way, with its longitudinal axis passing through the ball's north and south poles.
And so, (getting to the point at last), the business about changing the radius of the cylinder is really meaning that the geometric solid used to model the human body is not a proper cylinder which one describes with two parameters (radius and height), but is something else. One possible something else you might mean is that along the length of this solid the cross-section is always half a cylinder, but the radius changes with position. Or you might mean that the object isn't actually a cylinder, but something whose surface at any point along the length is described by a radial function r(theta).
makes rocket science look easy
my business in ABQ was at Sandia. Far as I know they don't do rocket science, so maybe you were visiting Kirkland. Don't tell, I know, it's a secret.
