The inner radius of a pipe is 2.1 cm. How much water can 12 m of this pipe hold?

The inner radius of the pipe = 2.1 cm

Length of the pipe = 12 m = 1200 cm

Volume of the pipe

\[\begin{array}{*{35}{l}}

=\text{ }\pi {{r}^{2}}h\text{ }=\text{ }22/7\text{ x }{{2.1}^{2}}~x\text{ }1200  \\

=\text{ }16632\text{ }c{{m}^{3}}  \\

\end{array}\]
