sphere, spheroid, ellipsoid
An hemisphere is half of a globe with a circular flat base, a round edge, a curved surface but no vertices.
A sphere. A sphere is a solid figure that has no faces, edges, or vertices. This is because it is completely round; it has no flat sides or corners.
0 for the faces, edges, and vertices because it is round. Hope that helps! :D
edges = 4 round base + 4 from vertices of base to apex = 8 edges corners = 4 round base + 1 apex = 5 vertices
None but it has 2 round edges
None but it has 2 round edges
A cylinder has three faces and two round surfaces.
Circular round face= 1 Flat faces= 1 Edges= 1
There is one face on the base and 4 round the edge (from each bottom edge to the top vertex) giving 5 faces in all.There are 4 edges round the square base and one edge from each of the 4 vertices of the base to the top vertex, giving 8 edges in all.There are 4 vertices round the square base plus another one at the top, giving 5 vertices in all.As a check, this obeys Eulers formula: Faces + Vertices = Edges + 25 + 5 = 10 = 8 + 2
Spheres are the only shapes that have no vertices. A sphere is a three-dimensional shape that is perfectly round, with all points on its surface equidistant from its center. Unlike other three-dimensional shapes such as cubes or pyramids, spheres do not have any corners or vertices where edges meet.
A cone has 1 flat surface, because a cone has 1 corner and has 4 edges. The reason that is is because a cone is round. A cone has a flat surface at the bottom of the cone. The reason it is because the cone doesn't have any vertices and most of the solid and plane figures have vertices.
A sphere has 0 edges and 0 faces. Thus implying that it has no verticies either. This is obvious. Spheres are round.
