Question

volume of cylinder
$volume of cylinder$
​

Answer 1

$V = \pi \: r {}^{2} h$

$r = radius$

$h = height$

Answer 2

Pie* (r square)* h

For derivation you should first find out area of bottom i.e pie* (r square)



And now for volume of cylinder you should multiply it by H [ height of cylinder ]
Therefore :
Volume of cylinder => Pie* (r square)* h
