three people eat almost the same.

the diameter of an 8-inch pizza is: 21.32 cm. Generally speaking, how many inches of pizza we are talking about is actually inches in the British system, not inches in the city system. 1 inch ≈2.54 cm, and 1 inch is about 3.33 cm. So the diameter of an eight-inch pizza is 8x2.54=21.32 cm.

the origin of pizza:

"pizza" is a kind of food with Italian flavor made of special sauce and stuffing, but in fact, this kind of food has surpassed the barriers of language and culture and become a global snack, which is loved by consumers all over the world. But when and where this kind of food originated, it is hard to know. So who invented pizza? ?

origin: in the 3rd century BC, Roman history records: round wheat cake+olive oil+spices+baking on a stone.

Pizza comes from bread, and bread plays an important role as a staple food in western history. It is not always the same in the long flow of time, but by adding different ingredients to better meet people's needs and hobbies. Historians discovered a similar transitional food from bread to pizza 3111 years ago in Sardinia, Italy.

the innovation of pizza still comes from the addition of tomatoes (in fact, there is another kind of fish, which is replaced by tomatoes). Naples is the first to bring about this change, which can be said to be the origin of modern pizza.

But it was a Neapolitan chef who made a pizzaMargherita specially for Queen Savoia in 1889 and named it after the Queen.
