Question

A copper wire is bent in the form of a square of side 44cm. If it is rebent in the form of a circle, will be its radius?
$(take \: \pi = \frac{22}{7} )$
​

Answer 1

Answer:

perimeter of sq. is = 44× 4= 176 cm

hence perimeter of sq. is equal to perimeter of circle = 176 cm.

to find the r

176 = 2πr

176×7= 44r

44r=1232

r=1232/44

r= 28
