    Question

    A cone has a radius of 6 cm and a slant height of 10 cm.

    What is the approximately surface area of the cone?
    A 250 cm² Correct Answer Incorrect Answer
    B 301 cm² Correct Answer Incorrect Answer
    C 360 cm² Correct Answer Incorrect Answer
    D 262 cm² Correct Answer Incorrect Answer

    Solution

    Surface area of a cone = πr(l + r), where r is the radius and l is the slant height. Substituting the values: Surface area = π × 6 × (10 + 6) = π × 6 × 16 = 96π cm² ≈ 301 cm².
