The same wire is not bent in the form of a circle. Find the area enclosed by the circle. Area of the circle = 484 cm2 ⇒ 484 = Side2 ⇒ 222 = Side2 ⇒ Side = 22 cm Perimeter of the square = 4 × Side Perimeter of the square = 4 × 22 = 88 cm Length of the wire = 88 cmCircumference of the circle = Length of the wire = 88 cmNow, let the radius of the circle be r cm. Thus, we have: 2πr = 88 `⇒ 2xx22/7xx"r"=88` ⇒ r = 14 Area of the circle = πr2 `=22/7xx14xx14` = 616 cm2 Thus, the area enclosed by the circle is 616 cm2.
