Question

A wire is bent in the form of a square whose area is 1089 metre square. If the same wire is bent in the form of a circle, find the area of the circle

Answer 1

The area will remain the same as the same wire is bent to form a circle.

Answer 2

Answer:

Step-by-step explanation:

Given: a square of area= 1089m.sqr.

To find : area of circle

Sol:as area of sqr = side^2

=>1089=side^2

=> side=33m

As same wire is used to make a circle

=>side of sqr = circumference of circle

=>33m=2pi×r

=>33=2×22/7×r

=>21/4m = r

Now ,

Area of circle = pi × r^2

= 22/7×21/4×21/4

=86.625m^2
