Can I pls get help on this

Answer:
19 in pie is the best option
Step-by-step explanation:
what I did was found the area of the pies. I wasn't 100% sure on if the size was the radius or diameter but I used it as the radius. anyway I found the area of the pies using a = πr^2 then I took those numbers and divided it by how much the pie costed in total. this answer gave me how much each square inch of pie i would get for my money.
