Question

A copper wire is bent in the form of a square with area 121cm2.if the same wire is bent in the form of the circle,the radius of the circle is

Answer 1

radius of the circle is 7 cm.
please mark it as brainliest answer.

Answer 2

Area of square = 121 = s2
Therefore s = 11

Now,

Length of the wire= 11 x 4 (4 sides of square) = 44 cm

This becomes circumference of circle

C = 2 x pi x r

44 = 2 x 22/7 x r
By solving, we get
R = 7
