1 really. You cannot denote any specific sides or faces as it has to be uniform to be a sphere
It has no CURVED faces.
sphere
One if it is solid, two if it is hollow
The section of a cone or sphere or ellipsoid or paraboloid slice by two planes.
There is 1 curved surface on a sphere
A sphere.
a sphere :)
It has 2 because it has a curved face and a flat based face
sphere cylinder cone hemisphere
sphere, cylinder and a cone
It has no CURVED faces.
sphere
Two. One which is flat and the other which is curved.
The tetrahedron has only four faces. A sphere has only one, but that's probably not what you meant since the surface of a sphere is curved.
A sphere has no faces and no edges. It is a three-dimensional object with a curved surface and only one continuous boundary.
it has 0 curved faces
A sphere has no edges, because an edge is defined as where two faces meet. Likewise, it has no faces, because a face is defined as the flat surface of an object. Likewise, it has no corners either.
