integral from 0 to 7 of pi(2sqrt(3y))^2

\int_{0}^{7} π (2 3 y)^{2} d y

π 294

Decimal

923.62824 \dots

Solution steps

\int_{0}^{7} π (2 3 y)^{2} d y

Take the constant out:

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

= π \cdot \int_{0}^{7} (2 3 y)^{2} d y

Apply Integration By Parts

= π [12 y^{2} - \int 12 y d y]_{0}^{7}

\int 12 y d y = 6 y^{2}

= π [12 y^{2} - 6 y^{2}]_{0}^{7}

Simplify

= π [6 y^{2}]_{0}^{7}

Compute the boundaries:

294

= π 294

\int_{0}^{1} 3 x e^{x} d x

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

\int_{0}^{9} \frac{x}{9 + 3 x} d x

\int_{1}^{x} x^{4} d x

\int_{6}^{9} \frac{1}{x ^{2}} d x
