\begin{array}{r} h = & 4 \\ r = & 2 \end{array}

$\begin{array}{r} h = & 4 \\ r = & 2 \end{array}$

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 = 2

$r = 2$ and height

h = 4

$h = 4$ into the formula to find the volume of the cylinder. Pi

π

$π$ is approximately equal to

3.14

$3.14$ .

π \cdot 2^{2} \cdot 4

$π \cdot 2^{2} \cdot 4$

Step 3

Raise

2

$2$ to the power of

2

$2$ .

π \cdot 4 \cdot 4

$π \cdot 4 \cdot 4$

Step 4

Move

4

$4$ to the left of

π

$π$ .

4 \cdot π \cdot 4

$4 \cdot π \cdot 4$

Step 5

Multiply

4

$4$ by

4

$4$ .

16 π

$16 π$

Step 6

The result can be shown in multiple forms.

Exact Form:

16 π

$16 π$

Decimal Form:

50.26548245 \dots
