Sphere vs Hemisphere — Comparison Table
| Basis | Sphere | Hemisphere |
|---|---|---|
| Definition | Complete round 3D ball shape | Half of a sphere |
| Surfaces | One curved surface | One curved and one flat circular surface |
| Volume | (4/3)πr³ | (2/3)πr³ |
| Surface Area | 4πr² | 3πr² (curved + flat base) |
| Examples | Earth, basketball, marble | Dome, bowl, half of Earth |
Key Points
- A sphere is a complete round object with all points equidistant from center
- A hemisphere is exactly half of a sphere
- A hemisphere has one flat circular base and one curved surface
- Both are important 3D shapes used in architecture, geography, and engineering
