integral from 0 to 2 of pi(3x)^2

\int_{0}^{2} π (3 x)^{2} d x

24 π

Decimal

75.39822 \dots

Solution steps

\int_{0}^{2} π (3 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} (3 x)^{2} d x

Simplify

(3 x)^{2} : 9 x^{2}

= π \cdot \int_{0}^{2} 9 x^{2} d x

Take the constant out:

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

= π 9 \cdot \int_{0}^{2} x^{2} d x

Apply the Power Rule

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

= π 9 [\frac{x ^{3}}{3}]_{0}^{2}

Compute the boundaries:

\frac{8}{3}

= π 9 \cdot \frac{8}{3}

Simplify

= 24 π

\int_{0}^{2 π} 2 cos (t) sin (t) d t

\int_{0}^{2} r^{2} sin (θ) d r

\int_{3}^{4} x^{π - 1} d x

\int_{0}^{\frac{π}{12}} cos (6 t) d t

\int_{1}^{2} e^{x} + \frac{1}{x} d x
