Question

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

Answer 1

circumference of circle=perimeter of square
2πr=4×side
2×22/7×42=4×side
66=side
Hence the length of side of square is 66cm

Answer 2

Step-by-step explanation:

$radius = 42cm$

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

$= 2x$

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

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

$so.$

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

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

$264 = 4 \times side$

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

$side = 66cm$
