Question

A wire is in the shape of a square of side 44cm.if it is refolded into a circular ring, find the radius of the ring

Answer 1

perimeter of square= 4 x side
= 4x 44 =176 cm

now this perimeter becomes the circumference of circle.

circumference = 2 x 22/7 x radius
176 = 2x 22/7 x radius
radius =176 x 7/ 2x22
radius = 28 cm

Answer 2

Answer:

Perimeter of square=4*side

4*44

176 m.

Perimeter of circle=2πr

2*22/7*r =176

44/7*r = 176

44*r =176*7

44*r =1232

r = 1232/44

r =28
