Small Pizza- radius 6 in. cost $9.75

Medium- radius 8in cost $12
Large-diameter 20 in cost $16.50

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?

------------

so i find the area of all the pizza, how do i find the cost per slice? per dollar?

Small- area- 113.04
Medium- area-200.96
Large- area -314
what do i do next? Thanks :)

It is edge (or circumference) per dollar you want, not area in this case

so divide each circumference by the cost to find the edge per dollar.

(I do not agree that the edge is the best, but so be it)

1.

C = pi * d
C = 3.14 * 12
C = 37.68

9.75 / 37.68 = $0.259 per per inch

Follow the same procedure for the medium and large pizzas to find the cost per inch of circumference.

2. Into how many pieces will you divide each pizza?

medium- $0.238

large- $0.262

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

What is the surface area with a dimeter of 40mm and the height is 16mm?

To find the cost per slice, you need to divide the total cost of the pizza by the number of slices it can be divided into. Since the question asks for the cost per dollar, we'll divide the total cost by the number of dollars.

First, let's find the number of slices in each pizza size.

Small Pizza:
The small pizza has a radius of 6 inches, so its diameter is 2 times the radius, which is 12 inches. It doesn't mention the number of slices, so we'll assume it can be divided into 8 slices. (However, you may want to confirm this with the pizza shop if you're looking for an exact number of slices.)

Medium Pizza:
The medium pizza has a radius of 8 inches, so its diameter is 2 times the radius, which is 16 inches. It doesn't mention the number of slices, so we'll assume it can be divided into 12 slices. (Again, confirm with the pizza shop if you need an exact number.)

Large Pizza:
The large pizza has a diameter of 20 inches. It doesn't mention the number of slices, so we'll assume it can be divided into 16 slices. (Confirm with the pizza shop if needed.)

Now let's calculate the cost per slice and cost per dollar for each pizza size:

Small Pizza:
Cost per slice = $9.75 / 8 slices = $1.22 per slice
Cost per dollar = $9.75 / $9.75 = $1 per dollar

Medium Pizza:
Cost per slice = $12 / 12 slices = $1 per slice
Cost per dollar = $12 / $12 = $1 per dollar

Large Pizza:
Cost per slice = $16.50 / 16 slices ≈ $1.03 per slice
Cost per dollar = $16.50 / $16.50 = $1 per dollar

Now, to find the size that has the most pizza edge per dollar, we need to calculate the circumference of each pizza. The circumference is the distance around the edge of the pizza.

Circumference of Small Pizza:
C = 2πr = 2π * 6 inches ≈ 37.7 inches

Circumference of Medium Pizza:
C = 2πr = 2π * 8 inches ≈ 50.3 inches

Circumference of Large Pizza:
C = πd = π * 20 inches ≈ 62.8 inches

From the calculations, the large pizza has the most pizza edge per dollar as the cost per dollar is the same for all pizzas. Its circumference is approximately 62.8 inches.
