Question

A wire in the shape of a square of side 44 cm is bent so as to form a circular ring. Find the radius of the circle

Answer 1

4a=2πr

hence u can find r, because length of the wire is same....

Answer 2

Answer:

The radius of the circle is 7 cm.

Step-by-step explanation:

Given : A wire in the shape of a square of side 44 cm is bent so as to form a circular ring.

To find: The radius of the circle?

Solution :

Length of the wire is 44 cm when it is bent in the form of circle the length will become the circumference of the circle.

Now, Circumference of the circle is 44 cm.

Circumference of the circle is $C=2\pi r$

Substitute,

$44=2\times \frac{22}{7}\times r$

$r=\frac{44\times 7}{2\times 22}$

$r=\frac{7}{1}$

$r=7cm$

Therefore, The radius of the circle is 7 cm.
