\begin{matrix} h = & 9 r = & 8 \end{matrix}

$\begin{array}{r} h = & 9 \\ r = & 8 \end{array}$

Step 1

The volume of a cylinder is equal to the area of the base

π r^{2}

$π r^{2}$ times the height.

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

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

Step 2

Substitute the values of the radius

r = 8

$r = 8$ and height

h = 9

$h = 9$ into the formula to find the volume of the cylinder. Pi

π

$π$ is approximately equal to

3.14

$3.14$ .

π \cdot 8^{2} \cdot 9

$π \cdot 8^{2} \cdot 9$

Step 3

Raise

8

$8$ to the power of

2

$2$ .

π \cdot 64 \cdot 9

$π \cdot 64 \cdot 9$

Step 4

Move

64

$64$ to the left of

π

$π$ .

64 \cdot π \cdot 9

$64 \cdot π \cdot 9$

Step 5

Multiply

9

$9$ by

64

$64$ .

576 π

$576 π$

Step 6

The result can be shown in multiple forms.

Exact Form:

576 π

$576 π$
