Question

find the capacity of the cylindrical container with internal diameter 28 centimetre and height 20 centimetre

Answer 1

d=28cm
h=20cm
r=d/2 = 28/2 = 14cm
v = $\pi$ r^2 h 
= 22/7*14*14*20
=12320cm^3 
1cm^3=1/1000l
therefore 12320cm^3 = 12320/1000=12.32 l 

Answer 2

Hey there!!
This is Aishwary !!


let r be the radius and h be the height of the cylinde
Given that -
r = 28/2 = 14 cm

h = 20 cm

Volume / capacity of cylindrical container = πr^2h

=> 22/7×14×14+20

=> v = 12320 cm^3
=> v = 12320/1000 = 12.320 ltrs^3

Hence the capacity of the container is 12.320 ltr^3

Hope this helps u !!
