Question 1106516
each slice has a central angle of 40 degrees.


360 / 40 = 9 slices from each pizza.


there are 20 people and each person needs to get 2 slices of pizza.


that would be 40 slices of pizza.


40 / 9 = 4.44........ pizzas.


round up to the nearest whole pizzas, and you need 5 pizzas.


5 * 9 = 45 slices of pizzas.


each person gets 2 slices for a total of 40 slices.


there will be 5 slices left over for whoever wants them.


4 pizzas * 9 = 36 slices which isn't enough.


5 pizzas * 9 = 45 which is more than enough.
