It depends how big you want your slices to be. say one slice is a 3 by 4 rectangle. you would get about 4 slices, plus 2 smaller slices. Or, you could make them half the size and get about 10. It all depends how big they're going to be.
The slices can range 9 to 24. Most sicilian pizzas are cut into 16 squares. However, it can differ based on the size of the pie.
It all depends how big you want to slice the pieces :). I would say 8 slices is a nice amount. If everyone is very hungry it will probably be 4 slices.
It will depend on the size of the portions you wish to serve but around 12 slices.
A 9-inch pie typically yields about 6 to 8 servings, depending on how generous the slices are. For dessert pies, 8 slices are common for a standard serving size, while savory pies may be cut into larger portions. Ultimately, the number of servings can vary based on the pie's filling and the appetite of the guests.
54 ÷ 6 = 9 slices on each plate.
This would depend on the size of the pie. A normal 9-inch pie will generally provide six servings, unless everybody is on a diet, in which case eight servings. So 25 people divided by 6 servings would be five pies, with five slices left over. Or, you could cut thinner slices and get by with four pies. A smaller pie of about 6 inches in diameter will provide four servings, so you'd need seven pies.
As many as you want. You decide.
