\int_{0}^{3} π (4 5 y)^{2} d y

Entferne die Konstante:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= π \cdot \int_{0}^{3} (4 5 y)^{2} d y

Wende die partielle Integration an

= π [80 y^{2} - \int 80 y d y]_{0}^{3}

\int 80 y d y = 40 y^{2}

= π [80 y^{2} - 40 y^{2}]_{0}^{3}

Vereinfache

= π [40 y^{2}]_{0}^{3}

Berechne die Grenzen:
