A wire in the shape of a square of side 11cm is rebent into the shape of a circle . Find the area of the circle

Answer 1

hello frnd!

here's ur answer...

perimeter of square=circumference of circle

perimeter of square=side×4

=11×4

=44cm

therefore circumference of the circle will also be 44cm

2πr=44cm

2×22/7×r=44cm

44/7×r=44cm

r=44/1×7/44

r=7cm

area of the circle=πr²

=22/7×7×7

=22×7

=154cm²

hope this helps...
