Janie served 4 same zise pizzas at the class party. explain how to find how many slices of pizza janie served if the angle for each slice turns though a right angle

If each slice turns a right angle that means it turns 90 * so you can only have two turns per pizza which gives 4 slices (90+90+90+90=360 - this is how many degrees in a circle) so per pizza 4 slices. For four pizzas that is 4x4 which is 16 so 16slices
