# Math Help - Geometry Space: Cylinders

1. ## Geometry Space: Cylinders

A reservoir that takes the form of a straight cylinder contains a volume of water equal to $\frac{2}{3}$ of their capacity. If you were removed from 50 liters of liquid the height of their fall from 10%. The total volume of the reservoir, in liters, is:

2. $V_w=\frac{2}{3}V_r \Rightarrow V_r=\frac{3}{2}V_w$
$50 l$ - $0,1 V_w$
$500 l$ - $V_w$ (volume of water),
$V_r=\frac{3}{2}*500 l=750 l$
