Mona took wire of length 22 metre and bend it into the shape of circle find the area of circle also find its radius if the same wire is banned into the shape of a square what will be the length of each of its side which figure enclose more area the circle or the square.

It is bent to make a circle , so
Circumference of the circle = 22
2πr = 22
r == 3.5r=
The required radius = 3.5 m
Area = πr² = 22/7 × 3.5 × 3.5 = 38.5 m²
Then it is bent to make a square so ,
Perimeter = 22
4× Side = 22
Side = 22/4 = 5.5 m
Area = Side × Side = 5.5 × 5.5 = 30. 25 m²
