Answer 2

$\huge{\red{\underline{\underline{\rm{Answer:-}}}}}$

$\star{\large{\green{\underline{\sf{Given:}}}}}$

$\sf{\implies Diameter\;of\;cylinder=28\;m}$

$\sf{\implies Radius\;of\;cylinder=14\;m}$

$\sf{\implies Height\;of\;cylinder=7\;m}$

$\star{\large{\green{\underline{\sf{To\;Find:}}}}}$

$\sf{\implies How\;many\;kilo\;liters\;of\;water\;can\;cylinder\;hold.}$

$\star{\large{\green{\underline{\sf{Formula\;used:}}}}}$

$\sf{\implies Volume\;of\;cylinder=\pi r^{2}h}$

$\textsf{Now, put the values in the formula. We get,}$

$\sf{\implies Volume\;of\;cylinder=\pi r^{2}h}$

$\sf{\implies \dfrac{22}{7}\times 14\times 14\times 7}$

$\sf{\implies 22\times 196}$

$\sf{\implies 4312\;m^{3}}$

∴ As we know 1 m³ = 1000 liters.

So, 4312 m³ = 4312 × 1000 liters.

                    = 4312000 liters.

So, kiloliters = 4312000/1000

                    = 4312 kilo liters.

Hence, cylinder holds 4312 kilo liters of water.
