Question
The volume of cone is 2695 cm3. If its height
is 2.1 cm then find the radius of the cone.Solution
Let the radius of the cone be ‘r’ cm Therefore, (1/3) × (22/7) × r2 × 2.1 = 2695 Or, r2 = 2695 × (7/11) = 1225 Or, r = 35 (since, radius cannot be negative) Therefore, radius of the cone = 35 cm
