Basic Math Examples

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

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 $r = 4$ and height $h = 4$ into the formula to find the volume of the cylinder. Pi $π$ is approximately equal to $3.14$ .

$π \cdot 4^{2} \cdot 4$

Step 3

Multiply $4^{2}$ by $4$ by adding the exponents.

Step 3.2.1

Raise $4$ to the power of $1$ .

$π \cdot (4^{1} \cdot 4^{2})$

Step 3.2.2

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$π \cdot 4^{1 + 2}$

Step 3.3

Add $1$ and $2$ .

$π \cdot 4^{3}$

Step 4

Raise $4$ to the power of $3$ .

$π \cdot 64$

Step 5

Move $64$ to the left of $π$ .

$64 π$

Step 6

The result can be shown in multiple forms.

Exact Form:

$64 π$
