Question

the diameter of circular ring made by a where is 42 CM if the wire is bent to so to form a square find the side of the square ​

Answer 1

Answer:

Radius=21cm

circumference of circle = perimeter of square

2πr=4*side

2*22/7*21=4 *a (side =a)

44*3/4=a

a=33cm

Answer 2

Answer:

Diameter of ring= 42cm

Radius=21cm

Perimeter of circle=2πr

=2*22/7*21

=132cm

Perimeter of circle=Perimeter of square

132=4a

132/4=a

33=a

Then side of the square = 33 cm
