Answer:
12.83 inch^2
Step-by-step explanation:
To calculate the area of each piece, we need to first need to calculate the area of the pizza as a whole.
Mathematically the area A of the pizza can be calculated using the formula;
A = π * r^2
where our r here is 7 in
Thus, A = 22/7 * 7 * 7 = 154 inch^2
The area of each piece of the pizza is thus 154/12 = 12.8333333 inch^2
To the nearest hundredth, this is 12.83 inch^2
