Question

a copper wire is bent in the form of a sqare of side 44cm. if it is rebent in the form of a circle, what will be it's radius?

take π= 22/7​

Answer 1

Answer:

side of square=44

perimeter of square=44 x 4=176

after it was rebent into a circle, it will be the circumference of the circle

circumference of circle=2π r

                                 176=2x22/7xr

                                 176=44/7r

                                 176x7/44=r

                                  r=28

so the radius is 28 cm
