  1. Answer:

    radius=17.5cm

    Step-by-step explanation:

    The length of wire is the perimeter of square.

    length of wire= 4x side of square

    length= 4×27.5

    = 110

    then it is rebent into circle.

    length of wire is the circumference of circle

    110=2πr

    110=2×22/7xr

    110/2=22/7xr

    55×7/22=r

    r=17.5cm

    radius= 17.5cm
