Question

a wire is in the form of a circle of radius 42 centimetre it is bent into square find the side of a square take pie as 22 by 7

Answer 1

hello frnd!

here's ur answer..

circumference of circle=perimeter of square

given the radius of the circle is 42cm

hence it's circumference=2πr

=2×22/7×42

=1848/7

=264cm

therefore the perimeter of the square is also 264cm.

so side×4=264cm

→side=264/4

→side=66cm

verification:-

perimeter of square=side×4

=66×4

=264cm

hence verified

thus the side of the square is 66cm

hope this helps..!
