Answer 1

$\huge\underline\bold\color{red}\mathfrak{Answer}$

Length of the wire = 88 cm

It is bent in the shape of a circle. That is the circumference of the circle is equal to length of the wire = 88 cm

We know that,

Circumference of circle = 2πr

Substituting,

88 = 2×22/7 × r

88/2 = r × 22/7

44 = r×22/7

44 × 7/22 = r

2×7 = r

r = 14 cm

Radius of the circle = 14 cm.
