A cone would fit the given description
A paraboloid.
It's a rectangle.
A cone.
A cone.
cone
hemisphere
The shape of the face on a cone is a circular base at the bottom and a curved surface that narrows smoothly to a point called the apex. This curved surface is referred to as the lateral face of the cone. Overall, a cone has one circular face (the base) and one curved surface.
Yes, a cylinder has both curved and flat surface. Considering a solid cylinder standing on its end, the circular base and the circular top are flat surfaces. The surface connecting the top and bottom is curved.
A hemisphere has two surfaces: one curved surface and one flat circular base. The curved surface is the rounded part of the hemisphere, while the flat base is the circular face that lies on the ground or surface.
cornet
A paraboloid.
The shape with one circular base and one curved surface is a cone. A cone tapers smoothly from its circular base to a single point called the apex. It is commonly found in various contexts, such as ice cream cones and traffic cones.
