The radius was divided by 2.
31.4 = 2pi * r
31.4/2pi = 15.7/pi
15.7 = 2pi * r
15.7/2pi = 7.85/pi
(7.85/pi) / (15.7/pi) = 1/2

<h2>
Answer:</h2>
Option: D is the correct answer.
D: 18, because the number of catalogs is 72 over 5 divided by 4 over 5.
<h2>
Step-by-step explanation:</h2>
Let Freddy could arrange n catalogs on the shelf.
The dimension of the shelf is:
72 over 5 inches wide.
The dimension of the catalog is:
4 over 5 of an inch thick.
n × Dimension of one catalog=Dimension of shelf.
i.e.
n×(4 over 5 inches)=72 over 5 inches
i.e.
n=72 over 5 inches/ 4 over 5 inches
i.e.
n=72/4
i.e.
n=18
Hence, Freddy could arrange 18 books in the shelf.
