Question
The volume of a right circular cone is given as 1232
cm³, and its base area measures 154 cm². Determine the slant height of the cone.Solution
Volume of cone = Area of base X height ÷ 3 So, height of the cone = 1232 ÷ 154 X 3 = 24 cm Area of the base = πr2 (Where 'r' is the radius) 154 = (22/7) X r X r Or, r2 = 49 So, r = 7 (As radius cannot be negative) Slant height of cone = √(radius2 + height2) So, slant height = √(72 + 242) = √(49 + 576) = 25 cm
