    Question

    If the curved surface area of a cylinder is 126π cm²

    and its height is 14 cm. then, what is the volume of the cylinder?
    A 253.5π cm³ Correct Answer Incorrect Answer
    B 276.5π cm³ Correct Answer Incorrect Answer
    C 283.5π cm³ Correct Answer Incorrect Answer
    D 263.5π cm³ Correct Answer Incorrect Answer

    Solution

    given - height = 14cm  the curved surface area of a cylinder = 126 π 2πrh = 126π 2π × r× 14 =126π r = 9/2= 4.5 cm so now the volume of the cylinder = πr²h =4.5×4.5×14 × π =(9×9×7) π/2 =567π/2 =283.5π cm³
