integral from 0 to 2 of pix^2

\int_{0}^{2} π x^{2} d x

\frac{8 π}{3}

Decimal

8.37758 \dots

Solution steps

\int_{0}^{2} π 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_{0}^{2} x^{2} d x

Apply the Power Rule

: [\frac{x ^{3}}{3}]_{0}^{2}

= π [\frac{x ^{3}}{3}]_{0}^{2}

Compute the boundaries:

\frac{8}{3}

= π \frac{8}{3}

Simplify

= \frac{8 π}{3}

\int_{2}^{\infty} e^{- s t} d t

\int_{\frac{π}{6}}^{\frac{π}{2}} csc (x) d x

\int_{7}^{8} (\frac{5}{x ^{2}} - 1) d x

\int_{4}^{7} x d x

\int_{0}^{\frac{1}{4}} 0.9 e^{- 0.9 x} d x
