So Janie has 4 pizza.
How many individual slice can be served if they are right angles.

l______
Now if we are talking a pizza in the shape of a circle
A circle is 360 degrees around
This means we can fit 4, 90 degree right angles into 1 pizza.
So doing this math. 4, 90 degree pieces per pizza
And 4 pizzas
4 x 4 = 16
16 right angle slices can we served
Hope this helps!
