    Question

    A cone has a base radius of 7 cm and a slant height of

    25 cm. Find the total surface area of the cone.
    A 550 cm² Correct Answer Incorrect Answer
    B 572 cm² Correct Answer Incorrect Answer
    C 600 cm² Correct Answer Incorrect Answer
    D 704 cm² Correct Answer Incorrect Answer

    Solution

    Total surface area of a cone = π * r * (r + l), where r = radius and l = slant height. Given r = 7 cm and l = 25 cm. Total surface area = π * 7 * (7 + 25) = 22 * 32 = 704 cm². = 704 cm². Answer: d) 704 cm².
