Question

a wire is in the form of a circle of radius 42 cm.it is bent into a square determine the sides of the square

Answer 1

Radius of the circular wire = 42
Perimeter of the circular wire = 2(pi)r

==> 2×22/7×42
==> 2×22×6
==> 44×6
==> 264

Now According to the Question :-

Perimeter of the circle is equal to the perimeter of the square

Now,
Perimeter of the square = side × 4 = 264
Length of each side = 264/4 = 66

Answer 2

Answer:

$radius = 42cm$

$circumference \: or \: perimeter = 2\pi \: r$

$= 2x$

$\frac{22}{7} \times 42 = 2x$

$\frac{22}{6} = 264cm$

$so.$

$perimeter \: of \: squae \: is \: aslo \: 246cm$

$perimeter \: of \: square = 4 \times side$

$264 = 4 \times side$

$\frac{264}{4} = side$

$side = 66cm$
