$y = \frac{4}{3} π x^{3}$

Step 1

Combine $\frac{4}{3}$ and $π$ .

$\frac{d}{d x} [\frac{4 π}{3} x^{3}]$

Step 2

Since $\frac{4 π}{3}$ is constant with respect to $x$ , the derivative of $\frac{4 π}{3} x^{3}$ with respect to $x$ is $\frac{4 π}{3} \frac{d}{d x} [x^{3}]$ .

$\frac{4 π}{3} \frac{d}{d x} [x^{3}]$

Step 3

Differentiate using the Power Rule which states that $\frac{d}{d x} [x^{n}]$ is $n x^{n - 1}$ where $n = 3$ .

$\frac{4 π}{3} (3 x^{2})$
