The Snack Shack sells a large 18-inch pizza for $10.50. Which unit rate is greater than the price per square inch of the 18-inch pizza? Select all that apply.

A.
$0.02

B.
$0.03

C.
$0.04

D.
$0.05

E.
$0.06

F.
$0.07

Thanks for your help.

unit rate is price/area

area = pi r^2
So, figure your unit rate, and compare the choices

The answer can be: C, D, E, F

you sure??

welp, its 0.04

To find the unit rate of the price per square inch of the 18-inch pizza, we need to divide the price of the pizza by its area.

First, let's find the area of the pizza. The area of a circle can be calculated using the formula A = πr², where A is the area and r is the radius. Since the diameter of the 18-inch pizza is given, we need to divide it by 2 to find the radius.

So, the radius (r) of the pizza is 18 inches / 2 = 9 inches.

Now, let's find the area (A). We substitute the value of the radius into the formula A = πr².

A = π(9 inches)²
A = 81π square inches

Now, we can find the price per square inch by dividing the total price by the area.

Price per square inch = $10.50 / 81π square inches

To compare this value with the given options, we need to simplify it.

Price per square inch = $10.50 / 81π

Now, let's approximate this value using the given options.

Option A: $0.02
Option B: $0.03
Option C: $0.04
Option D: $0.05
Option E: $0.06
Option F: $0.07

To compare the options, we need to calculate the approximate value of the price per square inch.

Divide $10.50 by the approximate value of π (3.14) and then by 81:

Price per square inch ≈ $10.50 / (81 * 3.14)

Calculating this value, we find that the price per square inch is approximately $0.013.

Now we can compare this value to the given options to identify which ones are greater than the price per square inch.

Option A: $0.02 (Greater)
Option B: $0.03 (Greater)
Option C: $0.04 (Greater)
Option D: $0.05 (Greater)
Option E: $0.06 (Not greater)
Option F: $0.07 (Not greater)

Therefore, the unit rates that are greater than the price per square inch of the 18-inch pizza are:

A. $0.02
B. $0.03
C. $0.04
D. $0.05
