WebMost often used cone formulas when radius (r) and height (h) are known Slant height of a cone (s) = √ (r 2 + h 2) Base surface area of a cone (BA) = πr 2 Lateral surface area of a cone (LA) = πrs = πr√ (r 2 + h 2) Total surface area of a cone (TA) = LA + BA = πrs + πr 2 = πr (s + r) = πr (r + √ (r 2 + h 2 )) WebIf the height of the cone is 28m, then find the lateral surface area of frustum. Solution: Let, Radii are r1 = 10m and r2 = 3m Height, h = 24m First we need to find the slant height of frustum, by the formula: l = √ [ (r1 – … knotz hair studio new rochelle
