Answer:
No
Step-by-step explanation:
The relationship between the number of pies and the cost is not proportional. This is because the third pie is at half price, meaning it's not consistent with the price of the other two.
since the point (4,13) is on the circle, then the distance from the center to it, is the radius of the circle.
