Question

A wire is in the form of a circle of radius 42cm. It is bent into a square.​

Answer 1

$\huge \red{AηsωeR}$✍

Length of wire  =  circumference of circle

=2πr

=2×722×42=264 cm 

Length of wire  = Perimeter of square 

264=4a

So a=4264=66 cm

Side of equation =66 cm

Answer 2

Answer:

perimeter of radius =2πr

now, 2×22/7×42=264

now, perimeter os circle is equal to perimeter of square

therefore, 4s=264

s=66

this is the side of square
