Answer:
The artist used
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
![P=4a](https://tex.z-dn.net/?f=P%3D4a)
where
a is the length side of the square
![P=40\ in](https://tex.z-dn.net/?f=P%3D40%5C%20in)
so
![40=4a](https://tex.z-dn.net/?f=40%3D4a)
![a=10\ in](https://tex.z-dn.net/?f=a%3D10%5C%20in)
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
![C=\pi D](https://tex.z-dn.net/?f=C%3D%5Cpi%20D)
we have
![D=10\ in](https://tex.z-dn.net/?f=D%3D10%5C%20in)
substitute
![C=(3.14)(10)=31.4\ in](https://tex.z-dn.net/?f=C%3D%283.14%29%2810%29%3D31.4%5C%20in)
step 3
Find the difference
![40\ in-31.4\ in=8.6\ in](https://tex.z-dn.net/?f=40%5C%20in-31.4%5C%20in%3D8.6%5C%20in)
Answer:
37
Step-by-step explanation:
Landon is building new bookshelves for his book store
Each shelf can hold 33 books
There are 1221 mystery books
Therefore the number of shelves he will need to build can be calculated as follows
= 1221/33
= 37
Hence Landon will need to build 37 shelves
