integral from 0 to 9 of 81-x^2

Solution

\int_{0}^{9} 81 - x^{2} d x

Solution

486

Solution steps

\int_{0}^{9} 81 - x^{2} d x

Apply the Sum Rule:

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

= \int_{0}^{9} 81 d x - \int_{0}^{9} x^{2} d x

\int_{0}^{9} 81 d x = 729

\int_{0}^{9} x^{2} d x = 243

= 729 - 243

Simplify

= 486
