Answer:

-4

option d

is rigy

Step-by-step explanation:

1.54 m

Height of water level is 3 m.

Some water to a height of 4.5 METRES is poured into it.

\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)

✯ 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)
