Question

a wire is in the shape of a semi-circle of radius 28cm . if the wire is bent into a square. find its side. ​

Answer 1

Answer:

Radius of circle, r=28cm

then the circumference = 2πr

=2× 22 /7 ×28

=176cm

Let a be the side of the square,

circumference of circle = perimeter of the square

176=4a

a= 176/4 =44cm

area of square = a^2

=44^2

=1936cm^2

Hope this is helpful for you.
