Question

A wire is in the form of a circle of radius 42 cm.it is bent into a square determine the sides of the square

Answer 1

circumference of circle = perimeter of square

2 x pi x r            =      4 x s

2 x (22 / 7) x 42  =  4 x s

2 x 22 x 6         = 4 s

4 s           =   264

  side of the square = 264 / 4

             s     = 66

Answer 2

circumference = πd=22/7*42*2=22/7*84=264cm sq.
perimeter of square = 4*side=
264=4*side
side =264/4
side =6
