Question

you are in the shape of a square of side 22 centimetre is cut and went again in the form of a circle find the area enclosed by the circular wire

Answer 1

So wire forms a square of side 22 cm
so its length is perimeter of square
Perimeter of square of side x is
$4x$
So
$4x = 4(22) = 88$
This is the length of wire which will be perimeter of circle formed by wire
Perimeter of circle of radius r is
$2 \pi r$
$2 \pi r = 88 \\ \pi = \frac{22}{7} (approx) \\ r = \frac{88*7}{2*22} = 14$
Area of circle of radius r is
$\pi r^2 = \frac{22}{7} (14^2) = 616$
