Which do you think is a better illustration of a circle: a round pizza or a bicycle tire? Explain the reasons for your choice

Answer:a pizzaStep-by-step explanation:The key in this problem is the word circle. When we talk about a circle we talk about all points included within a circumference and this tells us about surface area. We know that the circumference stands for the points the same distance from the center but this doesn't tell us anything about the area. For a bicycle tire the points are made up from a material that can be rubber, but we haven't any rubber within that circumference, but air. Therefore, we can't calculate an area made of rubber as the area of a circle. So what about a pizza? well, a pizza has food within the circumference, that is, we can calculate an area made of food as the area of a circle [tex]\pi r^2[/tex]. In conclusion, a pizza is a better illustration for a circle.
