Question

Question #2. Find the cost per square inch of the NY Pizza rounded to the nearest cent.



$0.02 per square inch

$0.37 per square inch

$0.08 per square inch

$0.07 per square inch

Answer 1

The cost per square inch for the NY pizza is $0.08.

Explanation:

To solve this problem we first need to calculate the area of each pizza, since they're circular their area is given by:

area = pi*r² = pi*(d/2)²

Chicago:

area = 3.14*(14/2)² = 153.86 square inches

NY:

area = 3.14*(18/2)² = 254.34 square inches

The cost per square inch is given by the cost of the pizza divided by it's area. So for NY:

cost per square inch = 20.99/254.34 = $0.08 per square inch
