D)The relationship cannot be determined from the information given.
When a circle with radius \(r\) is inscribed in a square with side length \(a\), \(a = 2r\)
When a circle with radius \(r\) is inscribed in a rectangle with sides \(L\), and \(B\), \(r = \frac{L}{2}\) or \(\frac{B}{2}\) whichever is shorter
Col. A: \(π(\frac{a}{2})^2\)
Col. B: \(π(\frac{L}{2})^2\)
Col. A: \(a\)
Col. B: \(L\)
Hence, option A

Great information!
Col. A: \(π(\frac{a}{2})^2\)
Col. B: \(π(\frac{L}{2})^2\)
Col. A: \(a\)
Col. B: \(L\)
Hence, option A
