Question

A wire in shape of a circle of radius 10 cm, is rebent to form a square. Find the side of the square so formed
(Take n= 3.14)​

Answer 1

Step-by-step explanation:

The side of square formed is 15.7 cm.

Step-by-step explanation:

Given : A wire is in shape of circle of radius 10 cm It is rebent to form a square.

To find : The side of square so formed ?

Solution :

A wire is in shape of circle of radius 10 cm.

So, Length of the wire = circumference of the circle

i.e. l=2\pi rl=2πr

l=2\times 3.14\times 10l=2×3.14×10

l=62.8\ cml=62.8 cm

Wire is rebent to form a square.

So, Perimeter of square = length of wire

i.e. 4\times \text{side}=l4×side=l

4\times \text{side}=62.84×side=62.8

\text{side}=\frac{62.8}{4}side=

4

62.8

\text{side}=15.7side=15.7

Therefore, the side of square formed is 15.7 cm.
