A Circle if you mean 2d circle, 3d sphere =P Any continuously curves shape has no sides; ellipse (ellipsoid), cone, hyperbolic paraboloid...
No, it is not. For a cone, think of a standard ice-cream cone shape (or a witches hat) - a circular top OR base (but not both), which has sides coming off that taper into a point. Whereas a cylinder has a circular top AND base, (like the shape of baked bean cans), with sides joining both top and base.
There are no polygons (shapes with only straight-line sides) with fewer than three sides, but if you allow shapes with curved sides there are many possibilities. Examples include semicircles, annuli (donut shaped), and crescents.From Caromal, and Izzyk9God just say a CONE!!!
the cone has three sides

A cone only has a base, no sides
In a right circular cone the base is a circle and the sloped side is a sector of a circle. For a general cone, they are an ellipse and a sector of an ellipse.

A cone has no acute angles because a cone is a 3D shape and not a 2D.
It has 0 sides
cones have no congruent sides cause they dont have sides
Cinder-cone volcanoes are built by thick lava that is thrown high into the air and falls as chunks or cinders. These mountains form as a cone shape with narrow base and steep sides.

Neither. A cone is a cone.
A volcanic mountain with a narrow base and steep sides is typically called a volcanic cone or a cinder cone. These cones are formed from explosive eruptions that eject mostly tephra and volcanic ash, resulting in their characteristic steep shape.
