    Question

    Circumference of one of the bases of a right circular

    cylinder is 132 cm. If height of the cylinder is 15 cm more than its radius, then find the volume (in cm┬│) of the cylinder. (Use ╧А = 22/7)
    A 46,200 cm┬│ Correct Answer Incorrect Answer
    B 48,510 cm┬│ Correct Answer Incorrect Answer
    C 49,896 cm┬│ Correct Answer Incorrect Answer
    D 51,480 cm┬│ Correct Answer Incorrect Answer
    E 53,064 cm┬│ Correct Answer Incorrect Answer

    Solution

    Circumference of base of cylinder = 2 ├Ч ╧А ├Ч radius So,
    2 ├Ч (22/7) ├Ч radius = 132 Or,
    radius = 21 cm Height of the cylinder = 21 + 15 = 36 cm Therefore,
    Volume of cylinder = ╧А ├Ч radius┬▓ ├Ч height = (22/7) ├Ч 21┬▓ ├Ч 36
    = 49,896 cm┬│
