      Question

      The radius of the base of a cylindrical water tank is 7

      m and its height is 10 m. If the tank is 60% filled, then how much more water (in cubic metres) is required to fill it completely? (Take pi = 22/7)
      A 525 Correct Answer Incorrect Answer
      B 616 Correct Answer Incorrect Answer
      C 663 Correct Answer Incorrect Answer
      D 772 Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      Volume of cylinder = pi r2 h = (22/7) x 7 x 7 x 10 = 1540 cubic m Tank is 60% filled, so empty part = 40% Required water = 40% of 1540 = 616 cubic m Hence, the correct answer is 616.
