Question 76333
1.) Find total volume of the tank:
d=diameter of tank, h=length of tank
{{{V = .7854d^2h}}}
{{{V = .7854*(60^2)*(150)}}}
{{{V = .7854*(3600)*(150)}}}
{{{V = 424116 cc}}}

2.) Find out the remaining fluid volume in the tank after it leaks out:
If the tank diameter is 60 cm, and the valve is 20 cm off the ground, then the volume can be expressed as a fraction.
{{{20/60}}} = {{{1/3}}}

Therefore, {{{1/3}}} of the total fluid volume will remain in the tank;
so, total_volume * 1/3 = remaining_volume
{{{424116*1/3 = 141372 cc}}}
