Question

A wire is looped in the form of a circle of radius 28 cm. It is rebent into a square form. Determine the length of the side of the square.

Answer 1

Radius of the circle, $r=28cm$

We know,

Length of the wire = Circumference of the circle

$=2\times \frac{22}{7}\times 28=176cm$

Therefore,

Perimeter of the square = Length of the wire $=176$ cm

Therefore, the side of the square = $\frac{Lengthofwire}{4}=\frac{176}{4}=44cm$
