A cylindrical tank of diameter 35 cm is full of water. If 11 litres of water is drawn off, the water level in the tank will drop by-

Question

Answer 1

i think it is 11.43cms
because
1 dm^3=1L
11L=11dm^3
which is 11000 cm^3
equate it to volume of the cylinder formula;
11000=(22/7)*(35/2)^2*h
solving for h
h=100*4/35
=11.42857~11.43cms

Answer 2

i think it is 11.43cms
because
1 dm^3=1L
11L=11dm^3
which is 11000 cm^3
equate it to volume of the cylinder formula;
11000=(22/7)*(35/2)^2*h
solving for h
h=100*4/35
