Answer:
Wire is the form of rectangle 20cm long and 17.4cm wide.
As we are asked for radius of circle , we don't need to use 17.4cm in this question.
Because radius depends on length.
& length is given 20cm ie.
Perimeter of rectangle = Perimeter of Circle
20cm=2πr
r=10/π
Hence, radius of circle is 10/π.
