Schritte zur Lösung

\int_{0}^{9} π (x)^{2} d x

Entferne die Konstante:

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

= π \cdot \int_{0}^{9} (x)^{2} d x

Vereinfache

(x)^{2} : x

= π \cdot \int_{0}^{9} x d x

Wende die Potenzregel an

= π [\frac{x ^{2}}{2}]_{0}^{9}

Berechne die Grenzen:

\frac{81}{2}

= π \frac{81}{2}

Vereinfache

= \frac{81 π}{2}
