Question

a wire is bent to form a square of side 22 cm.if the wire is rebent to form a circle,its radius is :

Answer 1

Answer:

Step-by-step explanation:

Given:-

Side of a square=22cm

Now,

Perimeter of a square=4×a

=4×22

=88cm

A.Q.,

Perimeter of a square=perimeter of a circle

Perimeter of a circle=88cm

2πr=88

r=88/2π

r=14cm

Answer 2

Answer:

r = 14 cm

Step-by-step explanation:

Side of square = 22 cm

Perimeter of square = 4 x side

                                  = 4 x 22 cm = 88 cm

Perimeter of circle = 22 cm

Perimeter = 2πr

88 cm = 2 x 22/7 x r

r = 88 / 2π

r = 14 cm
