Zylinder
1. \(f(\rho \cdot \cos \varphi, \rho \cdot \sin \varphi, z)\)

2. \(dV' = \rho \cdot d \rho \cdot d \varphi \cdot dz\)

\(\int_{0}^{r} \: \int_{0}^{2\pi} \:\int_{0}^{h} \rho \, d \rho \, d \varphi \, dz\)

Kugel
1. \(f(r \cdot \sin \vartheta \cdot \cos \varphi,\:\:\, r \cdot \sin \vartheta \cdot \sin \varphi, \)
\(r \cdot \cos \vartheta)\)

2. \(dV' = r^2 \cdot \sin \vartheta \cdot dr \cdot d \vartheta \cdot d \varphi \)

\(\int_{0}^{2\pi} \: \int_{0}^{\pi} \: \int_{0}^{R} r^2 \sin \vartheta \:dr \,d \vartheta \, d \varphi\)
