    Question

    Circumference of one of the bases of a right circular

    cylinder is 176 cm. If height of the cylinder is 9 cm more than its radius, then find the volume (in cm³) of the cylinder. (Use π = 22/7)
    A 85,536 cm³ Correct Answer Incorrect Answer
    B 87,120 cm³ Correct Answer Incorrect Answer
    C 88,704 cm³ Correct Answer Incorrect Answer
    D 90,288 cm³ Correct Answer Incorrect Answer
    E 91,872 cm³ Correct Answer Incorrect Answer

    Solution

    Circumference of base of cylinder = 2 × π × radius So,
    2 × (22/7) × radius = 176 Or,
    radius = 28 cm Height of the cylinder = 28 + 9 = 37 cm Therefore,
    Volume of cylinder = π × radius² × height = (22/7) × 28² × 37
    = 91,872 cm³
