27. Q84: A circle is drawn inside a square having side as 'a' touching all the four sides of the square. Area of that circle will be
    Answer: C — πa²/4
    The correct answer is πa²/4. Key Points - A circle inscribed in a square touches all four sides, so its diameter equals the side of the square: d = a. - The radius is therefore r = a/2. - Area = πr² = π(a/2)² = πa²/4. Additional Information
