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. $\pi /2cm$
• B. $2\pi cm$
• C. 44 cm
• D. $(\pi +28)cm$

Answer 1

The correct option is C 44 cm

Given the radius of circle is 28 cm

Then circumference of the circle =$2\pi r=2\times \frac{22}{7}\times 28=176cm$

Let the side of cube is a cm

Then circumference of the cube=4a

$\therefore 4a=176\Rightarrow a=44$ cm

The side of cube =44 cm
