\begin{matrix} h = & 7 r = & 3.5 \end{matrix}

$\begin{array}{r} h = & 7 \\ r = & 3.5 \end{array}$

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 = 3.5

$r = 3.5$ and height

h = 7

$h = 7$ into the formula to find the volume of the cylinder. Pi

π

$π$ is approximately equal to

3.14

$3.14$ .

π \cdot {3.5}^{2} \cdot 7

$π \cdot {3.5}^{2} \cdot 7$

Step 3

Raise

3.5

$3.5$ to the power of

2

$2$ .

π \cdot 12.25 \cdot 7

$π \cdot 12.25 \cdot 7$

Step 4

Multiply

π

$π$ by

12.25

$12.25$ .

38.48451 \cdot 7

$38.48451 \cdot 7$

Step 5

Multiply

38.48451

$38.48451$ by

7

$7$ .
