Schritte zur Lösung

\int_{0}^{2} 9 - x^{2} d x

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{0}^{2} 9 d x - \int_{0}^{2} x^{2} d x

\int_{0}^{2} 9 d x = 18

\int_{0}^{2} x^{2} d x = \frac{8}{3}

= 18 - \frac{8}{3}

Vereinfache

18 - \frac{8}{3} : \frac{46}{3}

= \frac{46}{3}
