Question

a wire is bent in the form of a square which encloses an area of 121 CM square if the same wire is bent in the form of a circle then what will be the area of the enclosed figure​

Answer 1

Answer:

The answer is in picture

Answer 2

Given :----

• When the wire bent in the form of Square it enclose area of 121cm² .

Formula used :-----

• Area of square = side*side
• Perimeter of square = 4*side
• Perimeter of circle = 2πr
• Area of circle = πr²

Solution :-----

It is given that, area of square is 121cm²,

so,

→ (side)² = 121

→ side = 11cm ..

Now, same wire bent to Form a circle, that means that ,length of wire will be same in both case , only area will change ...

→ So, Length of wire with side 11cm = 11*4 = 44cm

Now, this is the length of Circle also,

→ so, 2πr = 44

→ 2*22/7*r = 44

→ r = 7cm .

Hence, Area of circle will be = πr² = 22/7 * 7 * 7 = 154cm² .

Hence, we can say that, area of circle would be 154cm² .
