Surface area of cone class 9
Surface area of a cone is the complete area covered by its two surfaces, i.e., circular base area and lateral (curved) surface area. The circular base area can be calculated using area of circle formula. The lateral surface area is the side-area of the cone. Let us see the formula to calculate the surface area of cone. See more The surface area of a cone is the total area occupied by its surface in a 3D plane. The total surface area will be equal to the sum of its curved surface area and circular base area. See more Consider a cone as a triangle that is being rotated about one of its vertices. Now, think of a scenario where we need to paint the faces of a conical flask. Before painting, we need to know the quantity that is required to paint all … See more The slant height of the cone is the distance from the vertex to the edge of the circular base of the cone. The vertical height is the distance from the vertex to the center of circular … See more WebJan 4, 2024 · The concept of Lateral/Curved area is also important in class 9 Surface Areas and Volumes. The area of only the curved part is known as the curved surface area or in case of cuboids or cubes, it is the area of only four sides leaving the base and top. For shapes like cylinder or cone, it is known as the lateral surface area. What is Volume?
