We are given that a wire, when bent into the shape of a square, encloses an area of 484 cm². We need to find the area enclosed when the same wire is bent into a circle. Step 1: Find the Side of the Square The area of a square is given by: \text{Area} = s^2 s^2 = 484 s = \sqrt{484} = 22 \text{ cm} Step 2: Find the Perimeter of the Square The perimeter of a square is: \text{Perimeter} = 4s = 4 \times 22 = 88 \text{ cm} Since the wire remains the same, its length when bent into a circle will also be 88 cm, which becomes the circumference of the circle. Step 3: Find the Radius of the Circle The circumference of a circle is given by: \text{Circumference} = 2\pi r 88 = 2\pi r r = \frac{88}{2\pi} = \frac{44}{\pi} \approx \frac{44}{3.1416} \approx 14 \text{ cm} Step 4: Find the Area of the Circle The area of a circle is: \text{Area} = \pi r^2 = \pi \left(\frac{44}{\pi} ight)^2 = \pi \times \frac{1936}{\pi^2} = \frac{1936}{\pi} Approximating: = \frac{1936}{3.1416} \approx 616 \text{ cm}^2 Final Answer: The area enclosed by the wire when bent into a circle is approximately 616 cm².

Hi
@siddannanivalagi5146 ?
We are given that a wire, when bent into the shape of a square, encloses an area of 484 cm². We need to find the area enclosed when the same wire is bent into a circle.
Step 1: Find the Side of the Square
The area of a square is given by:
\text{Area} = s^2
s^2 = 484
s = \sqrt{484} = 22 \text{ cm}
Step 2: Find the Perimeter of the Square
The perimeter of a square is:
\text{Perimeter} = 4s = 4 \times 22 = 88 \text{ cm}
Since the wire remains the same, its length when bent into a circle will also be 88 cm, which becomes the circumference of the circle.
Step 3: Find the Radius of the Circle
The circumference of a circle is given by:
\text{Circumference} = 2\pi r
88 = 2\pi r
r = \frac{88}{2\pi} = \frac{44}{\pi} \approx \frac{44}{3.1416} \approx 14 \text{ cm}
Step 4: Find the Area of the Circle
The area of a circle is:
\text{Area} = \pi r^2
= \pi \left(\frac{44}{\pi}
ight)^2
= \pi \times \frac{1936}{\pi^2}
= \frac{1936}{\pi}
Approximating:
= \frac{1936}{3.1416} \approx 616 \text{ cm}^2
Final Answer:
The area enclosed by the wire when bent into a circle is approximately 616 cm².
