    The area of a square is 3,600 cm². Find the area of a

    circle whose radius is (2/3)ᵗʰ of the side of the square. (Use π = 3.14)
    A 4,826 cm² Correct Answer Incorrect Answer
    B 5,163 cm² Correct Answer Incorrect Answer
    C 5,256 cm² Correct Answer Incorrect Answer
    D 5,024 cm² Correct Answer Incorrect Answer

    Solution

    ATQ,

    Area of square = side²

    ⇒ side² = 3,600

    ⇒ side = √3600 = 60 cm

    Radius = (2/3) × 60 = 40 cm

    Area of circle = 3.14 × 40² = 3.14 × 1,600 = 5,024 cm²
