Question

A brass wire of a circular shape with radius $\frac{2}{\pi }$ is bent into square. Determine the side of square.

• A. $2$
• B. $1$
• C. $\frac{1}{2}$
• D. None of the above

Answer 1

The correct option is B $1$

Perimeter of both figure is same
$P_c=P_s$

$2\pi r=4a$

$a=\frac{\pi r}{2}$

$a=\frac{\pi \times 2}{\pi \times 2}=1$ unit
