    Question

    The radius of the base of a cylinder is 14 cm and its

    curved surface area is 880 cm². Its volume (in cm³) is: (Takе π = 22/7)
    A 1078 Correct Answer Incorrect Answer
    B 3080 Correct Answer Incorrect Answer
    C 9240 Correct Answer Incorrect Answer
    D 6160 Correct Answer Incorrect Answer

    Solution

    Height of the cylinder = 2πrh = 880 ⇒ 2 × (22/7) × 14 × h = 880 ⇒ h = 10 cm The volume of the cylinder ⇒ (22/7) × (14)2 × 10 ⇒ 6160 cm3 ∴ The volume of the cylinder is 6160 cm3.
