Multiple choice general knowledge math & puzzles 0 Col A Col B Both are equal Can't be determined Reveal answer Fill a bubble to check yourself A Correct answer Explanation Area of square = M^2. Area of circle = π(M/2)^2 = (π/4)M^2. Since π is approx 3.14, π/4 is approx 0.785. Because M^2 > 0.785M^2 for any positive M, the area of the square (Col A) is always greater.
