One curved surface (two if it is hollow) and no edges.
A solid that has only curved surfaces is a cylinder or a sphere. However, the sphere is the most common example of a solid with exclusively curved surfaces, as it is perfectly round and has no flat faces. In contrast, a cylinder has two flat circular bases in addition to its curved surface.
Sphere, ellipsoid, torus, paraboloid, hyperboloid are shapes with only curved surfaces. Hemisphere, quadrant, cone and cylinder are examples of shapes with curved and plane surfaces. There are, of course, many others.
A shape that is not a polyhedron is a sphere. Unlike polyhedra, which are three-dimensional shapes with flat polygonal faces, a sphere has a curved surface with no edges or vertices. Other examples include cylinders and cones, which also possess curved surfaces and do not meet the criteria for polyhedra.
The radius of curvature of a spherical surface is the radius of the sphere from which the surface is derived. It is defined as the distance from the center of the sphere to the surface at any point. For a perfect sphere, the radius of curvature is constant and equal to the sphere's radius. This concept is crucial in optics and geometry, as it helps determine how light rays behave when they encounter curved surfaces.
A sphere has one continuous curved surface.
It is curved
There is 1 curved surface on a sphere
How about a cylinder, a cone and a sphere
One.One.One.One.
One curved surface (two if it is hollow) and no edges.
sphere, cylinder, cone
A cone, cylinder and a sphere are three examples.
Sphere, ellipsoid, torus, paraboloid, hyperboloid are shapes with only curved surfaces. Hemisphere, quadrant, cone and cylinder are examples of shapes with curved and plane surfaces. There are, of course, many others.
A sphere has just one curved face.
It doen't have any surfaces
A shape that is not a polyhedron is a sphere. Unlike polyhedra, which are three-dimensional shapes with flat polygonal faces, a sphere has a curved surface with no edges or vertices. Other examples include cylinders and cones, which also possess curved surfaces and do not meet the criteria for polyhedra.
