      Question

      The volume of cone is 1617 cm3. If its height

      is 3.5 cm then find the radius of the cone.
      A 35 cm Correct Answer Incorrect Answer
      B 36 cm Correct Answer Incorrect Answer
      C 27 cm Correct Answer Incorrect Answer
      D 21 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— 3.5 = 1617 Or, r2 = 1617 Γ— (7/11) = 441 Or, r = 21 (since, radius cannot be negative) Therefore, radius of the cone = 21 cm
