Question

a wire along its the boundary of a circle with radius 28 if the same wire is bent in the form of square find 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. 
= 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
