Basic Math Examples

 $\begin{array}{r} h = & 2 \\ r = & 1 \end{array}$

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 $h = 2$ into the formula to find the volume of the cylinder. Pi $π$ is approximately equal to $3.14$ .

$π \cdot 1^{2} \cdot 2$

Step 3

One to any power is one.

$π \cdot 1 \cdot 2$

Step 4

Multiply $π$ by $1$ .

$π \cdot 2$

Step 5

Move $2$ to the left of $π$ .

$2 π$

Step 6

The result can be shown in multiple forms.

Exact Form:

$2 π$

Decimal Form:

$6.28318530 \dots$
