Tangyuan is a subtle concept in math books. It is usually used to refer to the volume of a sphere or cylinder. Tangyuan can also be used for mathematical calculation, which is an important method to calculate the volume. In mathematical solid geometry, dumplings are usually used to describe the shape and size of spheres or cylinders, which is helpful to calculate their volume and surface area.

Tangyuan is not only used to calculate the volume and shape in mathematics, but also plays a key role in physics, astronomy and other disciplines. For example, astronomers may use jiaozi to calculate the size and shape of planets, while physicists may use jiaozi to calculate the mass and density of objects. The concept of glutinous rice balls is widely used in various fields.

In daily life, glutinous rice balls are also people's favorite food. There are many ways to package jiaozi, which can fully reflect the flavor characteristics of different regions. Whether it is delicious dumplings or salty dumplings, it can make people drool. In addition, jiaozi has special significance in traditional festivals in China, such as Lantern Festival and Winter Solstice Festival. It is not only a delicious dish, but also an important part of China culture.
