WebExample 2: Find the total surface area of the frustum of a right circular cone of height 20 in, large base radius to be 25 in, and slant height to be 29 in. Express the answer in terms of π. Solution: The large base radius of the frustum is, R = 25 in. Let its small base radius be 'r'. The height of the frustum of the cone is, H = 20 in. WebThe 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. Surface area of cone = πr (r+√ (h 2 +r 2 )) where r is the radius of the circular base. h is the height of cone. Or.
Circular Cone Formulas in terms of radius r and height h: Volume of a cone: V = (1/3) π r 2 h. Slant height of a cone: s = √ (r 2 + h 2) Lateral surface area of a cone: L = π rs = π r√ (r 2 + h 2 ) Base surface area of a cone ( a circle ): B = π r 2. See more r = radius h = height s = slant height V = volume L = lateral surface area B = base surface area A = total surface area π = pi = 3.1415926535898 √ = square root See more This online calculator will calculate the various properties of a right circular cone given any 2 known variables.
