Given: Area of square =484cm2 Formula used: Area of square =side2 The perimeter of square =4×side Area of circle =πr2 The perimeter of circle =2πr Where, r= radius of the circle Calculation: Let ‘ r ’ be the radius of the circle. Area of square =side2 Side of the square ⇒√484=22cm Length of the square ⇒4×22=88cm Now, the wire is bent into the circle The radius of the circle ⇒2πr=88⇒r=14cm Area of circle ⇒πr2=(
