Yes unless told otherwise
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.
Half of a sphere with a circular base is called a Hemisphere.
A hemisphere has no edges. It has one curved surface that smoothly transitions from the curved side to its base.
A hemisphere has two surfaces: one curved surface and one flat circular base. The curved surface is the rounded part of the hemisphere, while the flat base is the circular face that lies on the ground or surface.
A solid hemisphere has two surfaces: one curved surface and one flat circular base. The curved surface forms the outer part of the hemisphere, while the flat base is the circular face at the bottom.
A cone or a hemisphere or circle
How about a hemisphere ?
No. A cone could be considered the limiting case of a pyramid, but a hemisphere is not, because the lines joining the base to the apex are not straight.
hemisphere
A cone. A hemisphere.
It has 1 circular edge at its base
A hemisphere is one example.
