Answer 2

Answer:

Hi friend here is the answer::

Let r be the radius of the circle

Then,. r = 42 cm

circular- shaped wire is rebent into a square shape

Perimeter of the square = circumference of the circle

4× side = 2πr

$4 \times side = 2 \times \frac{22}{7} \times 42 \: cm \\ \\ side = \frac{2 \times 22 \times 42}{7 \times 4} cm \\ \\ = 66 \: cm$

✅ Hence,the length of the side of the square is 66 cm
