Answer:
Given that side of the square is 22 cm
Perimeter of the square =4a
=4×22
=88 cm
As the same wire is used to form a circle then both will have same perimeter.
Perimeter of circle = Perimeter of square
⇒2πr=88
⇒2*22/7*r =88
⇒r=14 cm
Hence radius of the circle is 14 cm.
then,
Area of the circle =πr²
= 22 ×14×14
=616 cm
