Ex 11.4 | Question 5

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.


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 \(1\rm\,m.\)
