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 \(= h\)

Radius of the base

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

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

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