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

Your answer:-

1386 m^2

Explanation:

area of square = 1089 m^2

side =√1089=33 m

so ,the perimeter of square = circumference of circle = 4× side

4×33=132m

circumference of circle = 2πr=132 m

let the radius be r.

2×22/7×r=132

r=132×1/2×7/22

r=21 m

area of circle = πr^2=22/7×(21)^2

22/7×21×21=1386 m^2
