Answer 2

Answer:

186.34 cm^2

Step-by-step explanation:

Side of square=$\sqrt{146.41}$=12.1

Perimeter=4*12.1=48.4

Perimeter of square=Circumference of circle

48.4=2πr

r=24.2*$\frac{7}{22}$

=7.7 cm.

Hence r=7.7cm

Area of a circle=π$r^{2}$

                        =$\frac{22}{7}*7.7^{2}$

                        =186.34 or  9317/50

Hope this helps. Good day to you
