Answer
$8.792 cm^3$
Work Step by Step
Volume , $V=\pi r^2 h$
Write the differential form such as:
$dV=\dfrac{\partial V}{\partial r} \times dr + \dfrac{\partial V}{\partial h} \times dh$
This gives: $dV=[ 2 \pi r h] dr+[ \pi r^2] dh$
Now, need to plug the given data.
$dV=[ 2 \pi \times 2 \times 10] \times (0.05)+4 \times (0.2)$
Thus, we get $dV=\dfrac{14 \pi}{5} cm^3$
or, $dV=8.792 cm^3$
