Answer 1

Required Answer:-

Given:

• A copper wire when bent in the form of a square, encloses an area of 484 cm².
• The same wire is bent in the form of a circle.

To find:

• The radius of the circle.

Answer:

• The radius of the circle is 14cm (Option A)

Solution:

We have,

➡ Area of Square = 484cm²

➡ Length of each side = √484 cm

➡ Length of each side of square = 22 cm.

Therefore, perimeter of the square will be,

= 4 × 22 cm

= 88 cm

➡ Length of rod = 88 cm ★

If the same wire is bent into the form of a circle, then it's perimeter will be equal to the length of rod.

➡ Perimeter of circle = 88 cm.

Let radius be r.

➡ 2πr = 88

➡ 2 × 22/7 × r = 88

➡ r = 88 × 7 / 44

➡ r = 14 cm.

★ Hence, the length of the radius of the circle is 14 cm. So, option A is the correct answer.
