integral from 1 to 3 of r^2

\int_{1}^{3} r^{2} d r

\frac{26}{3}

Decimal

8.66666 \dots

Solution steps

\int_{1}^{3} r^{2} d r

Apply the Power Rule

: [\frac{r ^{3}}{3}]_{1}^{3}

= [\frac{r ^{3}}{3}]_{1}^{3}

Compute the boundaries:

\frac{26}{3}

= \frac{26}{3}

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

\int_{0}^{1} 9 x^{8} (2 - x^{9}) d x

\int_{2}^{3} x^{4} + 4 x - 6 d x

\int_{0}^{a} \frac{b}{a ^{2}} (x - a)^{2} d x

\int_{4}^{- 4} 1
