Find the volume of the cone. Solution Given: Slant height, L= 25 mm radius, r = 12 mm L = √ (r 2 + h 2) By substitution, we get, ⇒25 = √ (12 2 + h 2) ⇒25 = √ (144 + h 2) Square both sides ⇒625 = 144 + h 2 Subtract by 144 on both sides. 481 = h 2 √481 = h h = 21.9

WebAnswer: The lateral surface area of the given cone is 1914 units 2. Example 2: Find the lateral area of a cone having height of 15 units and slant height of 17 units. (Use π = 3.14) Solution: Given that h = 15 units and l = 17 units. Radius of the cone (r) = √ (L 2 - h 2) = √ (17 2 - 15 2) = √ (289 - 225) = √64 = 8 units. good pillow for neck
