Answer:
π/4
Step-by-step explanation:
The area of the circle is A = π(2x)^2 = 4πx².
The length of one side of the square is 2(2x), or 4x, so the area of the square is A = 16x².
The ratio of the area of the circle to the area of the square is
4πx²
ratio = ------------- and this reduces to ratio = π/4.
16x²
