 $\begin{array}{r} h = & 1.25 \\ r = & 1.2 \end{array}$

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 $r = 1.2$ and height $h = 1.25$ into the formula to find the volume of the cylinder. Pi $π$ is approximately equal to $3.14$ .

$π \cdot {1.2}^{2} \cdot 1.25$

Step 3

Raise $1.2$ to the power of $2$ .

$π \cdot 1.44 \cdot 1.25$

Step 4

Multiply $π$ by $1.44$ .

$4.52389342 \cdot 1.25$

Step 5

Multiply $4.52389342$ by $1.25$ .

$5.65486677$
