Question

A copper wire when bent in the form of square enclosed an area of 121 if the same wire is bend into the form of a circle find the area of the circle

Answer 1

Answer:

Step-by-step explanation:You have not given any unit so i will do it as cm

Here the same copper wire is used to make a square and a circle.

Therefore,Perimeter of square= peri or circumference of circle

Here,we are given are of square=121cm2

Therefore,

Side2=121

Side=root over 121

Side=11cm

Now,

Perimeter of sq=4*side

=4*11

=44cm

Now,

Circumference of circle

2pier=44

2*22/7*r=44

44/7*r=44

r=7

Now, are of the circle

=pier2

=22/7*7*7

=22*7

=154cm2
