Vedclass · Answer

(B) The circumference of the circle is given by the formula $C = 2 \pi r$.Given $r = 42 \ cm$,the circumference is $C = 2 	imes \frac{22}{7} 	imes 42 = 2 	imes 22 	imes 6 = 264 \ cm$.Since the wire is bent into a square,the perimeter of the square is equal to the circumference of the circle.Perimeter of the square $= 4 	imes 	ext{side} = 264 \ cm$.Therefore,the side of the square is $\frac{264}{4} = 66 \ cm$.

$A$ wire is in the form of a circle of radius $42 \ cm$. It is bent into a square. The side of the square is? (in $cm$)
