The area of the circle is:
\(\left(7:2\right)^2.3,14=38,465\)
The area of the square is:
\(\left(\sqrt{\dfrac{7^2}{2}}\right)^2=\dfrac{49}{2}\)
So the answer is:\(\left|38,465-\dfrac{49}{2}\right|=\left|13,965\right|\approx13,97\)

The area of the circle is:
(7:2)2.3,14=38,465(7:2)2.3,14=38,465
The area of the square is:
(√722)2=492(722)2=492
So the answer is:∣∣∣38,465−492∣∣∣=|13,965|≈13,97
