a cone
A curved surface area can be described as one where the gradient of the normal to the surface changes smoothly from point to point.
A surface having no equivalent point at any plane
A cone.
cornet
A sphere
A tangent
No but a cone has a curved surface
No prism can have a curved surface.
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.
A curved surface of a lens can bend incoming light rays, focusing them to a point to form a clear image. The degree of curvature and the shape of the lens surface determine how the light is bent and where the focal point is located. This process is essential for the functioning of optical devices such as cameras, microscopes, and eyeglasses.
Yes, a cone has a curved surface, as it tapers smoothly from its circular base to a point at the top. In contrast, a pyramid has flat, polygonal faces and does not have a curved surface; its sides are made up of straight edges that meet at a vertex. Thus, only the cone exhibits a curved surface between its base and apex.
A solid with a curved surface is a sphere. Spheres are three-dimensional shapes where every point on the surface is equidistant from the center. Other examples of solids with curved surfaces include cylinders and cones, which have curved sides but flat bases. These shapes differ in their properties and dimensions but share the characteristic of having curves in their surfaces.
