63.585 cubic meters of soil were dug out to make the well.

<h3>How to find the how many cubic meters of soil were dug out to make the well?</h3>

given that

a cylindrical well is 25 meters deep and has a diameter of 1.8 meters.

height of cylinder is 25 meters.

radius of the cylinder is 0.9 meters.

now find the cubic meters of soil were dug out to make the well.

now volume of the cylinder is

volume= $\pi \: r {}^{2} h$

volume = $\frac{ 22}{7} \times {0.9}^{2} \times 25$

volume= $3.14 \times 0.81\times 25$

volume= $2.5434 \times 25$

volume= $63.585$

Hence, total cubic meters of soil were dug out to make the well is 63.585 ${m}^{3}$
