Question
The volume of cone is 2138.4 cm3. If its
height is 2.8 cm then find the radius of the cone.Solution
Let the radius of the cone be ‘r’ cm Therefore, (1/3) × (22/7) × r2 × 2.8 = 2138.4 Or, r2 = 2138.4 × (7/11) = 729 Or, r = 27 (since, radius cannot be negative) Therefore, radius of the cone = 27 cm
