Question

a wire is bent in the form of a square of area 1936cm square . if the same wire is bent to form a circle, find the radius and the area enclosed


​

Answer 1

$\huge\mathfrak\red{r = \frac{a}{2}}</p><p>$

$So,$

$\huge\mathfrak\red{r = \frac{1936}{2}}$

$\huge\mathfrak\red{r = 968}$

[Hope this helps you.../]

Answer 2

Answer:

Area of sqare = area of the circle

1936 = πr^2

1936 = 22/7 × r × r(because value of π is 22/7)

1936 ×7/22 = r^2

616 = r^2

√616 = r

24.82 = radius
