Find the Volume cylinder (21)(7)

 $\begin{array}{r} h = & 21 \\ r = & 7 \end{array}$

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 $r = 7$ and height $h = 21$ into the formula to find the volume of the cylinder. Pi $π$ is approximately equal to $3.14$ .

$π \cdot 7^{2} \cdot 21$

Step 3

Raise $7$ to the power of $2$ .

$π \cdot 49 \cdot 21$

Step 4

Move $49$ to the left of $π$ .

$49 \cdot π \cdot 21$

Step 5

Multiply $21$ by $49$ .

$1029 π$

Step 6

The result can be shown in multiple forms.

Exact Form:

$1029 π$

Decimal Form:

$3232.69884054 \dots$
