    Question

    A sector of a circle has a central angle of 120° and a

    radius of 10 cm. Find the area of the sector.
    A 55.5π cm² Correct Answer Incorrect Answer
    B 60π cm² Correct Answer Incorrect Answer
    C 75π cm² Correct Answer Incorrect Answer
    D 33.33π cm² Correct Answer Incorrect Answer

    Solution

    The area of a sector of a circle is given by: Area = (θ / 360) * πr², where θ is the central angle. Area = (120 / 360) * π * 10² = (1/3) * π * 100 = 100π / 3 ≈ 33.33π cm².
