Question

    The radius of a hemisphere is 10 cm. What is the total

    surface area of the hemisphere (including the base)?
    A 600 cm² Correct Answer Incorrect Answer
    B 942 cm² Correct Answer Incorrect Answer
    C 865 cm² Correct Answer Incorrect Answer
    D 768 cm² Correct Answer Incorrect Answer

    Solution

    The total surface area of a hemisphere is given by: Surface Area = 3πr² Substitute the radius: Surface Area = 3 × 3.14 × 10² Surface Area = 3 × 3.14 × 100 Surface Area = 942 cm² Correct Option: b
