Question

The circumference of the base of a cylindrical vessel is $132cm$ and its height is $25cm$. How many litre of water can it hold?

Answer 1

Let the radius of the vessel be $r$ and its height be $h$

$\Rightarrow$ circumference $=2\pi r=r=\frac{132}{2\pi }cm$

$h=25cm$

Volume $=\pi r^{2}h=\pi \times \frac{(66{)}^2}{{\pi }^2}\times 25=34681.5c{m}^3$

$=34.68L$ $[1c{m}^3=1mL]$
