Question

A wire in the shapes of square 2640m long
is restaphed as circle what is radius
of
a arcle formed​

Answer 1

Length of wire = Perimeter of Square= 2640 m

It is reshaped in a circle = Circumference of circle = 2640.

Circumference =

$2\pi \: r$

2640 = 2 × 22/7 × r

2640 = 44/7 r

2640 × 7/44 = r

r = 420 m
