Question

A wire is looped in the form of a circle of radius $28cm$. It is re-bent into a square form. Find the length of the side of the square $(\text{Take}\pi =\frac{22}{7})$

• A. $49cm$
• B. $28cm$
• C. $44cm$
• D. $176cm$

Answer 1

The correct option is C $44cm$

Length of the wire $=$ Circumference of wire
$=2\pi r=2\times \frac{22}{7}\times 28=176cm$
Since it is rebent in the form of a square
Perimeter of the square $=$ Circumference of
Wire $=176cm$
$\therefore$ Each side of the square $=\frac{176}{4}cm=44cm$
