Correct Answer: 38.50 cm ²

Solution : Given, the area of the square formed by copper wire = 30.25 cm ²
Area of square = s ² where s is the side of the square.
⇒ 30.25 = s ²
⇒ s = 5.5 cm
Now, total length of wire = 4s = 4 × 5.5 = 22 cm
Let $r$ be the radius of the circle.
Length of copper wire = Perimeter of circle formed
⇒ 4s = 2$\pi r$
⇒ 22 = $2(\frac{22}{7}) r$
⇒ $r$ = 3.5 cm
Area of required circle = $\pi r^2$
= $\frac{22}{7}\times 3.5\times 3.5$
= 38.50 cm ²
Hence, the correct answer is 38.50 cm ² .
