Therefore, after replacing n × s by P, we get S = A + 1/2 (P ×l) Let us now use this fact to derive the formula of the surface area of a cone How to derive the formula to get the surface area of a cone? For a cone, the base is a circle, so A = π× r2 P = 2...
The arc length of the sector is equal to 2 * π * r. The area of a sector –which is our lateral surface of a cone – is given by the formula: A(lateral) = (s * (arc length)) / 2 = (s * 2 * π * r) / 2 = π * r * s The formula can be obtained from proport...
