Question

    If the height of a cone is 7 cm and the diameter of the

    circular base is 12 cm, then its volume is (nearest to integer):
    A 254 cm³ Correct Answer Incorrect Answer
    B 284 cm³ Correct Answer Incorrect Answer
    C 264 cm³ Correct Answer Incorrect Answer
    D 274 cm³ Correct Answer Incorrect Answer

    Solution

    Height =7cm, diameter =12cm r =6cm Volume of the cone = (1/3) × π × r² × h   = (1/3) × π × 62 × 7 ⇒ (1/3) × (22/7) x 36 x 7 ⇒ 264 cm³ The volume of the cone is 264 cm³.
