    Question

    In each of the following questions, a question is followed by three statements numbered I, II and III. Read all the statements and answer accordingly.

    Find the volume of the cylinder? Statement I:

    Height of the cylinder is equal to the radius of the base. Statement II: Height of the cylinder is 40 m. Statement III: Area of the base is 660 sq. m.
    A Only I and III Correct Answer Incorrect Answer
    B Only I Correct Answer Incorrect Answer
    C Only III Correct Answer Incorrect Answer
    D Any of the two Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    From I and II : Height = 40 m radius = 40 m Then ,Volume of the cylinder = (22/7) 40 × 4 0× 4 0 sq. m From II and III : Volume = Area of the base × Height = 660× 4 0 sq. m From I and III: Area of the base = (22/7) × radius2 = 660 we can calculate radius then , From I: Radius is equal to the height so , radius = height Now we can calculate volume of the cylinder. Hence , Any of the two is enough to get the volume .
