A cone does not have any parallel lines
Suppose the radius of the sphere is R. The base of the cone is the same as the base of the hemisphere so the radius of the base of the cone is also R. The apex of the cone is on the surface of the hemisphere above the centre of the base. That is, it is at the "North pole" position. So the height of the cone is also the radius of the sphere = R. So the ratio is 1.

Well, honey, a cone can't roll in a straight line because of its shape. It's like asking a square to roll smoothly without wobbling. Physics just ain't gonna let that happen, sweetie. So, in short, no, a cone can't roll in a straight line.
a cone has 1 curvedsurface.
A cone has one curved surface.
A cone has either one or two surfaces and either one or no edges.
It has one.

A cone has two surfaces, one vertex and no edges.
1 edge and 2 surfaces
ther is 20 surfaces on a cone because the is 1 on it sharp part * * * * * In fact, one flat surface (and one curved one).
An empty cone (like an ice-cream cone) doesn't have any flat surfaces. It has two curved surfaces, one outside and one inside. A solid cone has a flat base, and one other curved surface.
It only has one. the face going around the cone is called the lateral surface
