sphere, cylinder, cone
2 flat and 1 curved
A triangular prism contains zero curved and 5 flat surfaces.
a sphere, of course!
a sphere
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.
One if it is solid, two if it is hollow
a hexagonal prism has 0 curved surfaces
2 flat and 1 curved
