Volume of cone = Area of base × height ÷ 3 So, height of the cone = 1232 ÷ 154 × 3 = 24 cm Area of the base = πr2 (Where ‘r’ is the radius) 154 = (22/7) × r × 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
? + 156 ÷ 3 × 7 = 35% of 400 + (13)2
