derivative of

7 π r^{2}

14 π r

Solution steps

\frac{d}{d r} (7 π r^{2})

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= 7 π \frac{d}{d r} (r^{2})

Apply the Power Rule:

\frac{d}{d x} (x^{a}) = a \cdot x^{a - 1}

= 7 π 2 r^{2 - 1}

Simplify

= 14 π r

x^{2} - 7

\frac{y ^{^{'}}}{y} = 6 x^{2}

\frac{d y}{d x}, y \cdot cos (x) = 2 x^{2} + 5 y^{2}

\int_{5}^{8} \frac{x}{x ^{2} + 6 x + 13} d x

\int_{\frac{1}{7}}^{5} 14 x ln (7 x) d x
