Question

a cooper wire is in the form of a circle with radius 35cm. it is bent into a square.then the side of the square is

Answer 1

let the side of the square = a cm
radius of the circle  =r = 35 cm
perimeter of the square = circumference of the circle

4a = 2πr

a = (2 *22*35)/(4*7)
a= 11*5
a = 55 cm
∴ side of the square = a = 55cm

Answer 2

Radius of the circle=35cm
Circumference=2πr=2×22/7×35=220cm
When the copper wire in the form of a circle is bent into a square then
Circureference of the circle=perimeter of the square
Let the side of the square be x
220=4x
x=220/4=55
The side of the square=55cm
