Answer: The answer is 2487.

Step-by-step explanation: I took the test.

Answer 2

To answer this question, we find first the area of the pizza (which is a circle) through the equation,
A = πD²/4
where D is the diameter. Substituting the known values to the equation,
A = π(12 in)²/4 = 113.04 in²
Then, we multiply the calculated value above to the amount of calorie per in².
amount of calorie = (113.04 in²)(22 cal/in²)
amount of calorie = 2486.88 cal
Therefore, each pizza will contain 2486.88 calories.
