 $\begin{array}{r} h = & 8.4 cm \\ r = & 1 cm \end{array}$

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 $r = 1$ and height $h = 8.4$ into the formula to find the volume of the cylinder. Pi $π$ is approximately equal to $3.14$ .

$π \cdot 1^{2} \cdot 8.4$

Step 3
