▸The sphere has a total surface area of about 314.16 cm².
- Total surface area: 314.16 cm². The lateral (side) surfaces account for 100.0% and the base(s) for 0.0% of the total.
- Surface area scales with the square of size: doubling every dimension quadruples the area while the volume increases eightfold.
- Keep all dimensions in the same unit before calculating. Mixing centimetres and inches is the most common source of error.
