Surface area of cone class 9
Did you know?
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 WebSlant height of a cone (l) = 21 m. and diameter of its base = 24 m. ∴ Radius (r) = = 12 m. Now total surface area = πr (l + r) Question 8. The area of the curved surface of a cone is 60π cm 2. If the slant height of the cone be 8 cm, find the radius of the base. Solution: Curved surface area of a cone = 6071 cm 2.
