Question

a wire is in the form of a square of side 27.5 CM if it is bent in the form of a circle what will be its radius

Answer 1

Answer:

perimeter of the wire= 4 x 27.5 = 150 cm.

circumference of the circle = perimeter of the square wire = 150

So , 2πr = 150

r =( 150 x 7 )/ (2 x 22)

=23.86 cm
