The edge is stuffed with cheese, and its the best part of the pizza/ What size has the most pizza edge pr dollar? what is the circumference of this pizza?

small- $0.259
medium- $0.238
large- $0.262

Then what do i do? I am kind of very confused.

    I agree with you cost per inch around the circumference.

    Go back to the question it is asking which has the most pizza edge per dollar.

    Small has circumference of 37.7 inches and costs $9.75, so the amount of pazza edge per dollar is

    37.7 inches/9.75 = 3.87 inches per dollar

    similarly

    medium 4.19 inches per dollar
    large 3.80 inches per dollar

    so which has the most pizza edge per dollar?

    what is the circumference of this pizza?

    The medium one has the most inches per dollar (4.19 inches per dollar). I'll leave you to work out the circumference.
