Question

a circular by piece of thin wire is converted into a square of side 5.5 CM if there is no gain or loss in its length find the radius of a circular wire

Answer 1

The same wire is converted

so

perimeter of square = circumference of circle

perimeter of square =4×side

=4×5.5

=22cm

circumference of circle=2×pie×r

22=2×22/7×r

r=22×7/2×22

r=3.5 cm

Answer 2

Answer:

The same wire is converted

so,

Perimeter of square=Circumference of circle

Perimeter of square=4*side

=4*5.5

=22cm

circumference of circle=2×π×r

=22=2×22/7×r

r=22×7/2×22

r=3.5cm
