Question

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

Answer 1

Answer:

Step-by-step explanation:

Radius of circle = 42cm

Perimeter of circle=πr²

= 22/7×42×42= 5544cm

Since wire is bend to form a sqaure,

perimeter of square= perimeter of circle

5544= 4s

s=5544/4

=1386

Answer 2

Step-by-step explanation:

$radius = 42cm$

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

$= 2x$

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

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

$so.$

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

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

$264 = 4 \times side$

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

$side = 66cm$
