I.m not absolutely sure if this comes under physics or maths, so apologies if I've put it in the wrong place.
It is well known that if a sphere is exactly enclosed by a cylinder, the area of the curved surface of the cylinder is equal to hat of the sphere.
Does this also apply if the cylinder encloses an ellipsoid, ie the surface created when an ellipse is rotated around one of its axes? Or does it only hold for spheres?
