Notice that 56° = 45° + 11°. Then
tan(56°) = sin(56°) / cos(56°)
… = sin(45° + 11°) / cos(45° + 11°)
… = (sin(45°) cos(11°) + cos(45°) sin(11°)) / (cos(45°) cos(11°) - sin(45°) sin(11°))
Recall that sin(45°) = cos(45°) = 1/√2, so we can cancel each term involving 45° :
tan(56°) = (cos(11°) + sin(11°)) / (cos(11°) - sin(11°))

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
