length of wire is 13.2cm
if it's converted into circle then
2πr = 13.2
r = 6.6/π cm
= 2.1 cm
and it's area is
πr² = π(6.6/π)²
= 43.56/π
= 13.86
if it's converted into circle then
2πr = 13.2
r = 6.6/π cm
= 2.1 cm
and it's area is
πr² = π(6.6/π)²
= 43.56/π
= 13.86

Total perimeter of triangle =a+b+c=4.4+4.4+4.4=13.2cm
so we know that perimeter's other name is circumference so
circumference =13.4cm
and circumference of circle=2πr=13.4cm
r=13.4/24x7/22=2.1318cm
