 $\begin{array}{r} h = & 8 cm \\ r = & 12 cm \end{array}$

Step 1

The volume of a cylinder is equal to the area of the base $π r^{2}$ times the height.

$π \cdot {(r a d i u s)}^{2} \cdot (h e i g h t)$

Step 2

Substitute the values of the radius $r = 12$ and height $h = 8$ into the formula to find the volume of the cylinder. Pi $π$ is approximately equal to $3.14$ .

$π \cdot 12^{2} \cdot 8$

Step 3

Raise $12$ to the power of $2$ .

$π \cdot 144 \cdot 8$

Step 4

Move $144$ to the left of $π$ .

$144 \cdot π \cdot 8$

Step 5

Multiply $8$ by $144$ .

$1152 π {(cm)}^{3}$
