523.599
Explanatory note about the result.
體積 = (4/3)πr³ = 523.599;表面積 = 4πr² = 314.159。
At a glance:V = (4/3)πr³; A = 4πr². Complements sphere-volume and circle.
Formula
V = (4/3)πr³.
A = 4πr².
How to Use
- Enter the radius.
- The tool returns volume and area.
Case Studies
r=3
V=36π≈113.1; A=36π≈113.1.
FAQ
Surface area from volume?
A = (36πV²)^(1/3); both depend only on r.
