Definition
The volume of a cone refers to the amount of space enclosed by a cone-shaped object. It can be calculated using the formula V = (1/3)πr^2h, where r represents the radius of the base and h represents the height.
Surface area refers to the total area covering all surfaces of an object. For cones, it includes both curved and flat surfaces.
Similarity: Similarity is a geometric concept that describes objects with the same shape but possibly different sizes. Cones can be similar to each other if their dimensions are proportional.
Frustum: A frustum is a geometric shape formed by slicing off the top of a cone with a plane parallel to its base. It has two bases, one smaller than the other, and a curved surface connecting them.
