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.
How about a hemisphere ?
A cone or a hemisphere or circle
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.
A cone. A hemisphere.
hemisphere
A hemisphere is one example.
It has 1 circular edge at its base
A hemisphere is half of a sphere. It is a three-dimensional shape with a flat base and a curved surface that extends up to a semicircular shape.
A hemisphere is half of a sphere. It is a three-dimensional shape that consists of a flat base and a curved surface that forms half of a complete sphere.
