Question

a cylindrical tank has a radius of 154cm .it is filled with water to a height of 3m .if more water is poured into it up to a net height of 4.5m,what will be the increase in the volume of water in KL?

Answer 1

height=3m =300 cm
Volume ( V1 ) of cylinder tank of height 3m =2πr(r+h)
= 2*22/7*154(154+300)
=44/7*154*454
=439472 cm^3
=439.472L (1000cm^3=1 L)
net height=4.5m=450cm
Volume ( V2 ) of cylinder tank of net height 4.5m =2πr(r+h)
=2*22/7*154(154+450)
=44/7*154*604
=584672 cm^3
=584.672 L
Volume increase =V2-V1
=584.672-439.472
=145.2 L
=0.1452 kL
HOPE THIS ANSWER HELP YOU
