Answer:
The artist used [tex]8.6\ in[/tex] more of silver wire
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
we know that
The Perimeter of the square is equal to
[tex]P=4a[/tex]
where
a is the length side of the square
[tex]P=40\ in[/tex]
so
[tex]40=4a[/tex]
[tex]a=10\ in[/tex]
so
Each side of the square has a length of 10 in
step 2
Find the circumference of the circle
The diameter of the circle is equal to the length of the side of the square
The circumference is equal to
[tex]C=\pi D[/tex]
we have
[tex]D=10\ in[/tex]
substitute
[tex]C=(3.14)(10)=31.4\ in[/tex]
step 3
Find the difference
[tex]40\ in-31.4\ in=8.6\ in[/tex]
