Question

A wire is looped in the form a circle of radius 28cm.It is re-bent to form a square.Determine the length of the square?

Answer 1

circumference of a circle = 2πr
                                    = 2*22/7*28
                                    = 2*22*4
                                    = 176
now,
   perimeter of square = circumference of a circle
                              = 176
Therefore,
      side of square = perimeter/4
                           = 176/4
                           = 44 answer.

Answer 2

Radius of the circle (r) = 28cm Circumference of the circle = 2πr = 2* 22/7* 28 cm = 2* 22* 4 cm = 44* 4 cm =176 cm Sum of all the sides of the square obtained from the circle = The circumference of the circle 4a = 176 cm => a = 176/4cm => a = 44cm Therefore side of the square = 44cm
