Question

A circular piece of thin wire is converted into a square of side 6.25 cm. if there is no loss or gain in its length, find the radius of the circular wire.

Answer 1

According to given question,

let the radius of circle be r .

Area of circle =area of square.

=pie*r^2=side×side

=22/7×r^2=6.25×6.25

=r^2=12.42

r=root12.42

:-)hope it helps u.

Answer 2

Answer:

The radius of the circular wire is    $r=\sqrt{12.42}$.

Step-by-step explanation:

Given : A circular piece of thin wire is converted into a square of side 6.25 cm. if there is no loss or gain in its length.

To find : The radius of the circular wire?

Solution :

Side of the square s= 6.25 cm.

Let the radius of circle be r

Area of circle = Area of square

$\pi r^2=s\times s$

$3.14 r^2=6.25\times 6.25$

$r^2=12.42$

$r=\sqrt{12.42}$

Therefore, The radius of the circular wire is  $r=\sqrt{12.42}$.
