Question

A wire in the form of radius 21cm it is bent into a square determine the side of the square

Answer 1

Answer- Understanding the statements is an important thing.
So, according to the question, if we go in a depth, circumference of circle is equal to perimeter of square.
Radius of Circle= 21 cm
Circumference= 2πr= 2×22/7×21=132 cm
So, perimeter of square= 132 cm
       4×side=132
        side=132÷4= 33 cm

So, side= 33 cm
