Question

a wire is bent in the form of a circle with radius 25 cm It is straightened and made into a square what is the length of a of the side of a square​

Answer 1

Wire is bent into a circle of r = 25 cm

So, Circumference of circle = Length of wire

Hence, Length of wire = 2πr = 2*3.14*25 = 157 cm

Now, When it is drawn into a square then ,

Perimeter of Square = 4a = 157

Hence, Length of side of square = 157/4 = 39.25 cm

Answer 2

Answer:

as everything required is given in the question , we can easily take radius of the circle and then put the value of circumference and take out side of the square.
