Answer 1

Answer : 616 cm²

Explaination : First of all let us find the perimeter of square which will be length of the copper wire used.

Let side of square be a then,

a² = 484 cm²

or a = 22 cm

Length of copper wire = 4 * 22 = 88 cm

Since same copper wire is used perimeter if circle is given by 2πr where r is the side of circle.

2πr = 88 cm

or r = 14 cm.

Hence area covered by circle = πr².

Or area covered = 616 cm²
