Answer:
perimeter of square of side 11cm=4*side
=4*11=44cm
perimeter of square of side 11cm=circumference of circleof radius r
then circumference of circle =44
2*22/7*r=44
44r/7=44
r/7=44/44
r/7=1
r=7cm
the area of the circle=22/7*r²
=22/*7²
=22*7
=154 cm²
the area of the circle is 154 cm²
I hope it will help you..
