I think it is D.
Step-by-step explanation:
The bottom is pounds so it's 1 pound. The cost is $4 as the unit price it would be 1 pound/ 4 dollars. You put money on top so yeah... I'm really sorry if it's wrong.

Formula for the perimeter of a quarter circle: C = ((pi x 2r) / 4) + 2r
C = ((3.14 x 18) / 4) + 18
C = (56.52 / 4) + 18
C = 14.13 + 18
C = 32.13 miles
Hope this helps! :)
