One curved surface (two if it is hollow) and no edges.
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.
The surface area of a polyhedron can be calculated by first calculating the area of each of its polygonal surfaces and adding these together.The surface area of some curved solids (sphere, cylinder, cone) can be calculated from formula but for most curved solids are more complicated and require integration.
Yes.
Flat surfaces: 6Curved surfaces: 0.
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.
It doen't have any surfaces
A sphere has just one curved face.
a hexagonal prism has 0 curved surfaces
