Question
The volume of cone is 1617 cm3. If its height
is 3.5 cm then find the radius of the cone.Solution
Let the radius of the cone be ‘r’ cm Therefore, (1/3) × (22/7) × r2 × 3.5 = 1617 Or, r2 = 1617 × (7/11) = 441 Or, r = 21 (since, radius cannot be negative) Therefore, radius of the cone = 21 cm
