Calculation of the areas of figures in space and on the plane is one of the priority tasks of geometry, which has practical application. Total surface area of frustum of cone = \(πL~(r~+~r’)~+~πr^2~+~πr’^2\) Solved Problem. The first step in tackling the problem is to split the right cone into two different parts; the circular base and the side area of the cone (the lateral area). The Surface Area has two parts: The Base Area = π × r 2; The Side Area = π × r × s; Which together makes: Surface Area = π × r × (r + s) Note: we can calculate s = √(r 2 +h 2) Example: h = 7 and r = 2. Solution: Given that: r = 3 cm h = 4 cm To find the total surface area of the cone, we need slant height of the cone, instead the perpendicular height. Use the Pythagorean Theorem to find the slant height . The lateral surface area of a cone is calculated using the formula, LSA =πr√(r 2 + h 2) square units. shapes formulas list online.
