Question

a circular wire of radius 21cm is reshaped to make a square. find the side of the square

Answer 1

hello frnd!!

here's ur answer...

given the radius of circular wire=21cm

circumference of circle=perimeter of square

circumference of the circular wire=2πr

=2×22/7×21

=44×3

=132cm

therefore the perimeter of square is also 132cm.

side×4=132cm

side=132/4

side=33cm

hence, the length of the side of square is 33cm.

hope this helps....

Answer 2

perimeter of circle = perimeter of square formeg

 2 *22/7*21 =  4 * s

 33 = s
