Question

A circular. wire of radius 21cm reshaped ro make a square .find the side of the square

Answer 1

Hii friend,

Radius of circular wire = 21 cm


Circumference of circular wire = 2πR = 2 × 22/7 × 21 = 2 × 22 × 3 => 44 × 3 = 132 cm

Perimeter of circular wire = Perimeter of square shaped wire


=> 132 = 4 × Side

=> Side = 132/4 = 33 cm


Hence,


The side of the square shaped wire is 33 cm



HOPE IT WILL HELP YOU...... :-)

Answer 2

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 it will help you.
