integral from 2 to 4 of pi(25-x^2)

\int_{2}^{4} π (25 - x^{2}) d x

π \frac{94}{3}

Decimal Notation

98.43656 \dots

Solution steps

\int_{2}^{4} π (25 - x^{2}) d x

Take the constant out:

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

= π \cdot \int_{2}^{4} 25 - 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

= π (\int_{2}^{4} 25 d x - \int_{2}^{4} x^{2} d x)

\int_{2}^{4} 25 d x = 50

\int_{2}^{4} x^{2} d x = \frac{56}{3}

= π (50 - \frac{56}{3})

Join

50 - \frac{56}{3} : \frac{94}{3}

= π \frac{94}{3}

\int_{0}^{6} x (x^{2} - 9) d x

\int_{0}^{3} (3 e^{2 x} - x^{2}) d x

\int_{0}^{1} 2 y e^{y} d y

\int_{- 1}^{2} ((2 - x^{2}) - (- x)) d x

\int_{1}^{9} \frac{1}{( x - 1 ) ^{\frac{2}{3}}} d x
