integral from 0 to 4 of pi(x)^2

\int_{0}^{4} π (x)^{2} d x

\frac{64 π}{3}

Decimal

67.02064 \dots

Solution steps

\int_{0}^{4} 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}^{4} x^{2} d x

Apply the Power Rule

= π [\frac{x ^{3}}{3}]_{0}^{4}

Compute the boundaries:

\frac{64}{3}

= π \frac{64}{3}

Simplify

= \frac{64 π}{3}
