Sphere Calculations ⚪
Provide radius to compute volume and surface area.
Key Facts
- Volume = 4/3 × π × r³
- Surface Area = 4 × π × r²
Formulas
- Volume
Volume = 4/3 × π × r³- r = radius. Volume measures space inside the sphere. - Surface Area
Surface Area = 4 × π × r²- Total area covering the sphere’s surface.
Applications 🌐
- Estimate material for globes, balls, or spherical decorations.
- Calculate painting or wrapping areas.
- Model spherical objects in simulations or projects.
