    Question

    The volume of cone is 1267.2 cm3. If its

    height is 2.1 cm then find the radius of the cone.
    A 30 cm Correct Answer Incorrect Answer
    B 24 cm Correct Answer Incorrect Answer
    C 27 cm Correct Answer Incorrect Answer
    D 33 cm Correct Answer Incorrect Answer

    Solution

    Let the radius of the cone be β€˜r’ cm Therefore, (1/3) Γ— (22/7) Γ— r2 Γ— 2.1 = 1267.2 Or, r2 = 1267.2 Γ— (7/11) = 576 Or, r = 24 (since, radius cannot be negative) Therefore, radius of the cone = 24 cm
