False
No, it is not.
A polyhedron is a solid object bounded by polygons. Polygons are plane shapes [bounded by straight lines]. The curved surface of a cone is not a polygon and so the cone is not bounded by polygons and therefore, a cone is not a polyhedron.
NO a cone is not a polyhedron as it has a curved surface. Similarly sphere and cylinders r 3D but not polyhedrons
True
False
Yes, a cone would fit such a description
No, a cone is not a tetrahedron. A cone is a three-dimensional geometric shape with a circular base and a pointed vertex. A tetrahedron, on the other hand, is a four-sided polyhedron with triangular faces.

A right circular cone is perfectly balanced on its circular base. Imagine a cone that has a circular base, but leans to one side - this is a non right circular cone.
True
A cone has a flat circular base
Examples of non polyhedron are cone cylinder spere
A Right Circular Cone is one wherein the base of the cone is circular and the axis of the cone is perpendicular to the base and passes through the center of the base and the vertex of the cone.
In a right circular cone a line from the vertex to the center of the circular base is perpendicular to the base. In an oblique circular cone that same line will not be perpendicular.
