<PRE><B>Question 1051753</B>
{{{ V = pi*r*h }}}
{{{ V }}} = volume in ft3 
{{{ r }}} = radius in ft
{{{ h }}} = height in ft
-----------------------
{{{ V = 3.1416*4*10 }}}
{{{ V = 3.1416*40 }}}
{{{ V = 125.664 }}} ft3
-------------------------
In terms of just units:
[ time in minutes ] = [ volume in ft3 ] / [ filling rate in ft3/min ]
{{{ 125.664/8 = 15.708 }}} min
Rounding off, it will take Jane
16 min to fill the tank
