Answer:
5.971 cm
Step-by-step explanation:
Use formula
for the area of the circle. Since the area of the circle is
then
![\pi r^2=56\\ \\r^2=\dfrac{56}{\pi}\\ \\r=\sqrt{\dfrac{56}{\pi}}](https://tex.z-dn.net/?f=%5Cpi%20r%5E2%3D56%5C%5C%20%5C%5Cr%5E2%3D%5Cdfrac%7B56%7D%7B%5Cpi%7D%5C%5C%20%5C%5Cr%3D%5Csqrt%7B%5Cdfrac%7B56%7D%7B%5Cpi%7D%7D)
A square is inscribed into the circle, then its diagonal is twice the radius. The diagonal of the circle is equal to
![d=2r=2\sqrt{\dfrac{56}{\pi}}\ cm](https://tex.z-dn.net/?f=d%3D2r%3D2%5Csqrt%7B%5Cdfrac%7B56%7D%7B%5Cpi%7D%7D%5C%20cm)
Let x cm be the length of the square side, then by Pythagorean theorem,
![x^2+x^2=d^2\\ \\2x^2=\left(2\sqrt{\dfrac{56}{\pi}}\right)^2\\ \\2x^2=4\cdot \dfrac{56}{\pi}\\ \\x^2=\dfrac{112}{\pi}\\ \\x=\sqrt{\dfrac{112}{\pi}}\approx 5.971\ cm](https://tex.z-dn.net/?f=x%5E2%2Bx%5E2%3Dd%5E2%5C%5C%20%5C%5C2x%5E2%3D%5Cleft%282%5Csqrt%7B%5Cdfrac%7B56%7D%7B%5Cpi%7D%7D%5Cright%29%5E2%5C%5C%20%5C%5C2x%5E2%3D4%5Ccdot%20%5Cdfrac%7B56%7D%7B%5Cpi%7D%5C%5C%20%5C%5Cx%5E2%3D%5Cdfrac%7B112%7D%7B%5Cpi%7D%5C%5C%20%5C%5Cx%3D%5Csqrt%7B%5Cdfrac%7B112%7D%7B%5Cpi%7D%7D%5Capprox%205.971%5C%20cm)
