A wire when bent in the form of a square encloses an area of 484 sq. cm. If the same wire is bent in the form of a circle, what is the area enclosed by it?1). 264 sq. cm2). 616 sq. cm3). 488 sq. cm4). 492 sq. cm

Answer»

Area of the square = 484 SQ. cm

Let each SIDE B x cm

X2 = 484

⇒ x = √484 = 22 cm

∴ Length of the wire = 4 × 22 = 88 cm

∴ Circumference of the desired circle = 88 cm

⇒ 2 × 22/7 × radius = 88

⇒ radius = 14 cm

⇒ Area = 22/7 × 14 × 14 = 616 sq. cm
