Answer 2

Answer :-

• The side of the square is 11 cm.

To find :-

• The side of the square made by the wire.

Solution :-

• Before finding the side of the square, let's find the perimeter of the circle!

Given that :-

• Radius of the circle = 7 cm.
• The same wire was again used to make a square.

Therefore,

• The perimeter (circumference) of the circle will be equal to the perimeter of the square.

We know that :-

$\underline{ \boxed{\sf Perimeter \: of \: a \: circle = 2 \pi r}}$

Where,

• r = Radius.

Here,

• Radius = 7 cm.
• π = 22/7.

Hence :-

$\longmapsto \rm Perimeter = 2 \times \dfrac{22}{ \not7} \times \not7$

$\rm\longmapsto Perimeter = 2 \times 22$

$\rm\longmapsto Perimeter = 44 \: cm$

----------------------------------------

• Now, let's find the side of the square!

We know that :-

$\underline{ \boxed{ \sf Perimeter \: of \: a \: square = 4 \times Side}}$

Here,

• Perimeter = 44 cm.

Therefore,

$\tt\longrightarrow44 = 4 \times Side$

$\tt\longrightarrow \dfrac{44}{4} = Side$

$\longrightarrow\tt11 \: cm = Side$

Thus :-

• The side of the square is 11 cm.
