    side of a square whose area is 2,025 cm². (Use π = 3.14)
    A 4,826.01 cm² Correct Answer Incorrect Answer
    B 5,163.25 cm² Correct Answer Incorrect Answer
    C 4,069.44 cm² Correct Answer Incorrect Answer
    D 5,024.55 cm² Correct Answer Incorrect Answer

    Solution

    ATQ,

    Area of square = side²

    ⇒ side² = 2,025

    ⇒ side = √2025 = 45 cm

    Radius = (4/5) × 45 = 36 cm

    Area of circle = 3.14 × 36² = 3.14 × 1,296 = 4,069.44 cm²
