      Question

      The circumference of the base of a cylindrical tank is

      44 cm, and the height of the tank is 10 cm. Find the volume of the tank. 
      A 1540 cm³ Correct Answer Incorrect Answer
      B 1450 cm³ Correct Answer Incorrect Answer
      C 1650 cm³ Correct Answer Incorrect Answer
      D 1320 cm³ Correct Answer Incorrect Answer

      Solution

      Circumference of the base of the cylinder = 2 X π X radius

      So, 2 X π X radius = 44

      So, 2 X (22/7) X radius = 44

      So, radius = 7 cm

      Volume of the cylinder = π X radius² X height

      So, required volume = (22/7) X 7 X 7 X 10 = 1540 cm³
