Question

A wire is in the form of a circle of radius-28 cm, then the side of the square into which it can be bent is

• A. $\frac{\pi }{2}$ cm
• B. $2\pi$ cm
• C. $44$ cm
• D. $(\pi +28)$cm

Answer 1

Answer: (C)

$44$ cm

Radius of the circle $=r=28$ cm
Circumference of the circle $=2\pi r=2\pi \left(28\right)=176$ cm
Perimeter of square will be same as circumference of the circle $=176$ cm
Let $s$ be the side of the square.
Hence, $4s=176$
$\therefore s=44$ cm
