## Text Solution

What is Known?

Volume of the cylinder and diameter of the base of the cylinder is given.

What is unknown?
Height of the cylinder.

Steps:

If the height of the cylinder $$= h$$

\begin{align}(r) = \frac{{140}}{2}\,{\rm{cm}} = 70\,{\rm{cm}}=0.7 \rm\,m\end{align}

Volume of the cylinder $$= \pi {r^2}h$$

Thus, height of the cylinder is $$1\rm\,m.$$
