      Question

      What is the capacity of a cylindrical tank? I.

      The radius of the base is half of its height, which is 14metres. II. The area of the base is 1296 sq metres and the height is 14 metres.  Each of the questions below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and give answer –
      A If the data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question. Correct Answer Incorrect Answer
      B If the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question. Correct Answer Incorrect Answer
      C If the data either in statement I alone or statement II alone are sufficient to answer the question. Correct Answer Incorrect Answer
      D If the data in both statement I and II together are not sufficient to answer the question. Correct Answer Incorrect Answer

      Solution

      H = 14 m, r = 14/2 = 7 m  ∴ Capacity of the cylindrical tank = πr²h = 22/7× 7 × 7 × 14 = 2156m³ From II.  Capacity of the cylindrical tank = (area of base) × h = (1296) × 14 = 18144 m³ So, we can find the answer either with statement I or statement II.
