This question is simple I'm a little confused on the specifics so I will try my best to help.
s=θ(r)
arc length = angle x radius
2.46888m(or 8.1 ft) = (π/3) x r

The 11 may represent the price of the magazine if all the magazines at a certain store are $11. Then the s may represent the price of a book because all the books at a bookstore are different prices.
Hope this helps
The answer will be 880/20 the simplified that is 44
I'm not 100% sure that this is correct but it's a 50 50
The first one is none of these
Second one is alternate interior (I am 100% sure on this one)
Third one is corresponding
Fourth one is alternate exterior (also 100% sure)
Fifth one is also corresponding
