Question
The volume of cone is 1597.2 cm3. If its
height is 1.4 cm then find the radius of the cone.Solution
Let the radius of the cone be ‘r’ cm Therefore, (1/3) × (22/7) × r2 × 1.4 = 1597.2 Or, r2 = 1597.2 × (7/11) = 1089 Or, r = 33 (since, radius cannot be negative) Therefore, radius of the cone = 33 cm
