Question

    The radius of the base of a cone is 6 cm, and its slant

    height is 10 cm. What is the surface area of the cone?
    A 180 cm² Correct Answer Incorrect Answer
    B 190 cm² Correct Answer Incorrect Answer
    C 301.44 cm² Correct Answer Incorrect Answer
    D 342.67 cm² Correct Answer Incorrect Answer

    Solution

    The surface area of a cone is given by the formula: Surface Area = πr(r + l) Substitute the values: Surface Area = 3.14 × 6 × (6 + 10) = 3.14 × 6 × 16 = 3.14 × 96 = 301.44 cm² Correct Option: c
