Question

    A cone has a base radius of 6 cm and a height of 8 cm. Find its volume and slant height (use π = 3.14).

    A Volume = 301.44 cm³, Slant height = 10 cm Correct Answer Incorrect Answer
    B Volume = 296.88 cm³, Slant height = 11 cm Correct Answer Incorrect Answer
    C Volume = 285.12 cm³, Slant height = 10 cm Correct Answer Incorrect Answer
    D Volume = 292.16 cm³, Slant height = 12 cm Correct Answer Incorrect Answer

    Solution

    Volume of cone = (1/3)πr²h = (1/3) * 3.14 * 6² * 8 = (1/3) * 3.14 * 36 * 8 = 301.44 cm³ Slant height = √(r² + h²) = √(6² + 8²) = √(36 + 64) = √100 = 10 cm Correct Answer: a) Volume = 301.44 cm³, Slant height = 10 cm
