$\begin{array}{r} h = & 5 \\ r = & 3 \end{array}$

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

$r = 3$ and height

$h = 5$ into the formula to find the volume of the cylinder. Pi

$π$ is approximately equal to

$3.14$ .

$π \cdot 3^{2} \cdot 5$

Step 3

Raise

$3$ to the power of

$2$ .

$π \cdot 9 \cdot 5$

Step 4

Move

$9$ to the left of

$π$ .

$9 \cdot π \cdot 5$

Step 5

Multiply

$5$ by

$9$ .

$45 π$

Step 6

The result can be shown in multiple forms.

Exact Form:

$45 π$

Decimal Form:

$141.37166941 \dots$
