Question 854976
Since everything is in feet or cubic feet, you can just focus on the numbers.


volume of cylinder tank:  {{{(22.5)pi*(9/5)^2}}} and notice diameter is cut in half to use radius.


How many of the {{{9.5}}} are in the {{{(22.5)pi*(9/5)^2}}} ?


{{{HowMany=(1/9.5)(22.5)pi(9/5)^2}}}
This will be a rational number of pi, but can be approximated to {{{highlight(7.674*pi)}}} barrels.  This is about 24.1 barrels.
