A circular cookie cake costs $14.13. If the diameter of the cookie cake is 6 inches, what is the approximate cost per square inch of the cookie cake? Use π = 3.14.

$0.13
$0.25
$0.50
$0.75

First, we need to find the area of the circular cookie cake using the formula A = πr^2, where r is the radius of the circle (half the diameter).

Given that the diameter is 6 inches, the radius would be 3 inches.
Using π = 3.14, the area would be A = 3.14 * 3^2 = 3.14 * 9 = 28.26 square inches.

Next, we calculate the cost per square inch by dividing the total cost ($14.13) by the total area (28.26 square inches):
Cost per square inch = $14.13 / 28.26 = $0.50

Therefore, the approximate cost per square inch of the cookie cake is $0.50.
