WebAnswer: Slant height, s = 10 m Example 2: The height and base radius of a circular cone measure 4 m and 3 m respectively. Calculate its slant height. Solution: To find: Slant height of cone Given: Height of cone = 4 m Base radius of cone = 3 m Using slant height … WebIts slant height is L = 26 in. We know that, L 2 = H 2 + (R - r) 2 26 2 = 24 2 + (22 - r) 2 676 = 576 + (22 - r) 2 100 = (22 - r) 2 Taking square root on both sides, 10 = 22 - r r = 12 Thus, the total surface area of the given frustum of a right circular cone is, TSA = πL (R + r) + π (R 2 + r 2) TSA = π (26) (22 + 12) + π (22 2 + 12 2) = 1512π

WebJan 26, 2024 · The slant height of the right circular cone is found by using the formula: \ (l = \sqrt { {r^2} + {h^2}} \) \ ( \Rightarrow l = \sqrt { {2^2} + { { (2\sqrt 3 )}^2}} \) \ ( \Rightarrow l = \sqrt {4 + 12} \) \ ( \Rightarrow l = \sqrt {16} = 4\) units We know that the curved surface area of the right circular cone is \ (πrl\).
