Question

A wire in the shape of a square of side 88 cm is bent so as to form a circular ring. Find the radius of circle

Answer 1

perimeter of a pipe=(4*88) cm =352 cm
circumference of a circular ring =352 cm
2* pi * r=352 cm
r=352*7/2*22 cm= 56 cm

Answer 2

Radius of circle = 56 cm

Step-by-step explanation:

Given,

A wire that was initially in the form of square is later on reformed in circular shape.

Side of square = 88 cm

Perimeter of Square = Length of wire

We know that,

$\bold {Perimeter\ of\ square = 4\times side}$

                                                      = $4\times 88$

                                                      = 352 cm

As wire is now bent in circular shape

Circumference of wire =$2\pi r$

According to question,  

Perimeter of square = Circumference of circle

⇒$352 = 2\pi r$

⇒$352 = 2\times \frac{22}{7}\times r$

⇒$352 = \frac{44}{7}\times r$

⇒$r = \frac{352\times 7}{44}$

⇒r = 56 cm

Hence,Radius of circle = 56 cm
