    Question

    Find the area of the sector of a circle with radius 14

    cm and central angle 90°.
    A 49 cm² Correct Answer Incorrect Answer
    B 49 cm² Correct Answer Incorrect Answer
    C 7π cm² Correct Answer Incorrect Answer
    D 14π cm² Correct Answer Incorrect Answer

    Solution

    The area of the sector is given by: Area of sector = (θ/360) × π × r², where θ is the central angle, and r is the radius. Given: r = 14 cm and θ = 90°. Area of sector = (90/360) × π × 14² = 1/4 × π × 196 = 49π cm² Correct option: B) 49π cm²
