What is the mass density and radius of a giant star?

Giant stars typically have a lower mass density compared to smaller stars like main-sequence stars due to their expanded outer layers. Their mass can range from about 1 to 10 times that of the Sun, while their radii can be 10 to 100 times larger than the Sun's radius. As a result, their mass density is significantly reduced, often falling between 0.1 to 1 gram per cubic centimeter. The specific values can vary widely depending on the star's stage in its life cycle and its exact classification as a giant star.
