$V (2 r) = \frac{4}{3} π r^{3}$

Step 1

Multiply $\frac{4}{3} (π r^{3})$ .

Tap for more steps...

Step 1.1

Combine $π$ and $\frac{4}{3}$ .

$V (2 r) = \frac{π \cdot 4}{3} r^{3}$

Step 1.2

Combine $\frac{π \cdot 4}{3}$ and $r^{3}$ .

$V (2 r) = \frac{π \cdot (4 r^{3})}{3}$

$V (2 r) = \frac{π \cdot (4 r^{3})}{3}$

Step 2

Move $4$ to the left of $π$ .

$V (2 r) = \frac{4 π r^{3}}{3}$

Step 3

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
