\begin{gathered} \\ {\bf{To\: Find\::}} \\ \end{gathered}

ToFind:

Increase in volume of water.

\begin{gathered} \\ {\bf{Solution\::}} \\ \end{gathered}

Solution:

As we know that,

✯ Volume of the cylinder, when water level is upto 3 m, is

\begin{gathered}\dashrightarrow\:\tt{(Volume)_1\:=\:\dfrac{22}{7}\times{(1.54)^2}\times{3}\:} \\ \end{gathered}

⇢(Volume)

1

=

7

22

×(1.54)

2

×3

✯ After water level increase upto 4.5 m, then it's volume is,

\begin{gathered}\dashrightarrow\:\tt{(Volume)_2\:=\:\dfrac{22}{7}\times{(1.54)^2}\times{4.5}\:} \\ \end{gathered}

⇢(Volume)

=

7

×(1.54)
