Question

A wire is in a circular shape of radius 28 cm. If it is bent in the form of square,what will be the area of the square formed ?

Answer 1

Circumference of circle = 2 pi r
= 2 * 22/7 * 28.
= 44*4
= 176 cm
Since square is made from same wire
therefore it will have same length
4s = 176
s = 176/4
s = 44cm
now area = s square
area. = 44*44
= 1936 cm square

Answer 2

circumference of circle =2 pi r

=2×22/7×28

=176

perimeter if square=4×side

176 =4×side

side=176÷4

side= 44

area of square=side×side

=44×44

=1936
