Answer: D) Both a relation and a function</h3>
=======================================================
Explanation:
A relation is any set of (x,y) points usually with some rule tying them together. Though that rule doesn't have to be present. We could simply have a set of points. The set of points we are given is a relation.
A function occurs when we don't repeat the x value. Visually if we had two points stacked on top of each other, then we wouldn't have a function since it fails the vertical line test. A function happens when all x inputs leads to exactly one y output. If we had say { (-4,0), (2,-6), (-4,3) } then this wouldn't be a function since x = -4 repeats itself.
Since none of the x values repeat themselves in our given set, this means we have a function.
Side note: Any function is a relation, but not the other way around.

convert answer into yards (divide by 36)
there was 13.6 yards of fabric in each roll.
It’s C. divide the diameter by 2 which is 12.2. then it’s pi • r^2. so 3.14 • 12.2^2 =467.36
