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

\int_{0}^{2} π (x)^{2} d x

π 2

Decimal

6.28318 \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

Simplify

(x)^{2} : x

= π \cdot \int_{0}^{2} x d x

Apply the Power Rule

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

= π [\frac{x ^{2}}{2}]_{0}^{2}

Compute the boundaries:

2

= π 2

\int_{0}^{2} (- 2 x + 4) d x

\int_{- 2}^{2} x^{3} e^{x} d x

\int_{1}^{e^{2}} ln^{2} (x) d x

\int_{2}^{5} \frac{x ^{4}}{25} d x

\int_{1}^{6} (1 + 2 x^{3}) d x
