Question
The volume of cone is 1320 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 = 1320 Or, r2 = 1320 × (7/11) = 900 Or, r = 30 (since, radius cannot be negative) Therefore, radius of the cone = 30 cm
