Question

A wire is in the form of circle with radius 42 cm .it is bent into square .find the side of the square

Answer 1

2πr = circumference
r=42
2πr= 2×22/7×42
2πr=264
4side of square= 264÷4=61.5

Answer 2

Step-by-step explanation:

$radius = 42cm$

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

$= 2x$

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

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

$so.$

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

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

$264 = 4 \times side$

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

$side = 66cm$
