Question

a wire in the form of a circle of radius 21 is wind into a a wind into a a square then the length of a diagonal of the square​

Answer 1

THE CIRCUMFERENCE OF CIRCLE =PERIMETER OF SQUARE

$2\pi \times 21 = 4s$

$2 \times 22 \div 7 \times 21 = 2\times 22\times 3 = 132$

PERIMETER =4S=132

THEN,

$s = 132 \div 4 = 33$

Therefore SIDE=33

DIAGONAL OF A SQUARE=√2×S

$\sqrt{2} \times s = 1.414 \times 33 = 46.662$

THEREFORE THE LENGTH OF THE DIAGONAL OF THE SQUARE =46.662
