Question

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

Answer 1

Radius of circle = 42cm
Length of the wire =2πr
=2*(22/7)*42=2*22*6
=264cm
Side of the square=Perimeter/4
=264/4
=66cm.
Hence, each side of the square will be 66cm
Hope this solution helps you ☺

Answer 2

Solution -  

According to Question,  

Circumference of circle = Perimeter of square  

∵ Circumference of circle = 2πr  

= [ 2 × 22/7 × 42 ] cm      [∵ π = 22/7]  

= [ 44 × 6 ] cm  

= 264 cm  

∵ Perimeter of square = 264 cm  

We know,  

Side of sq. = Perimeter/ 4  

∵ each side of square  

= 264/4 cm = 66 cm  

∴ Each side of square = 66 cm
