Cylinders
A shape with 1 vertex, 1 edge, 1 flat face, and 1 curved face is a cone. The vertex is the tip of the cone, the edge is the circular base where the flat face meets the curved surface, and the flat face is the circular base itself. The curved face extends from the base to the vertex.
2 plane faces, 1 curved face
A cone. It has a circle for the base, and a curved face tapering to a point.
sphere
False. Cylinders have a circle at each end and a curved surface between: think of a cigarette!
hemisphere
a cone
A cone?
A cone. The base is circular and curved, and the tip of the cone is the vertex.
There is only 1 curved face!
Prisms have polygonal cross sections and several rectangular lateral faces. Cylinders have circular cross sections and one curved lateral face.
