Volume of a Sphere
Formula for calculating the volume of a sphere with radius r.
別名: sphere volume, volume of a sphere, きゅうのたいせき
数式
V = (4/3) × π × r^3
変数
| V | Volume of the sphere (m³) |
|---|---|
| r | Radius of the sphere (m) |
| π | Pi (approximately 3.14159) (—) |
計算例
半径 r = 2 m の球の体積を求めよ。
V = \dfrac{4}{3} \pi r^{3}
V = \dfrac{4}{3} \pi \times 2^{3}
V = \dfrac{32}{3} \pi \;\mathrm{m}^{3}
