Question

A wire is bent in the form of a square whose area is 1089 m2

. If the same wire is bent in the

form of a circle, find the area of the circle.​

Answer 1

Answer:

A wire is bent into the form of a square whose area = 1089 m2

area of square= 1089

side2= 1089

side=√1089

side=33

perimeter of square= 4×s

perimeter=33×4

=132

132= perimeter of circle

2πr=132

2×22/7×r=132

22/7×r=132\2

r=66×7/22

r=21

area of circle = πr^2

=22/7×21^2

=1386m2
