A "done" typically refers to a specific term or concept in various fields, but it seems there might be a misunderstanding or typo in your question. If you were referring to "dome," it is a structure that resembles the upper half of a sphere, often used in architecture. If you meant "dawn," in a metaphorical sense relating to spheres, it doesn't directly correlate to spherical concepts.
If you are referring to geometric terms, the relationship between a "dome" and a "sphere" is that a dome is a convex structure that can be defined mathematically as a portion of a sphere. Domes are typically hemispherical, representing half of a sphere, and are used in many buildings, such as cathedrals and governmental buildings, for their aesthetic appeal and structural integrity.
If you're thinking of something else related to "done" and "sphere," please provide more context, and I'll be happy to assist!
