You can put this solution on YOUR website!
+V+=+pi%2Ar%2Ah+
+V+ = volume in ft3
+r+ = radius in ft
+h+ = height in ft
-----------------------
+V+=+3.1416%2A4%2A10+
+V+=+3.1416%2A40+
+V+=+125.664+ ft3
-------------------------
In terms of just units:
[ time in minutes ] = [ volume in ft3 ] / [ filling rate in ft3/min ]
+125.664%2F8+=+15.708+ min
Rounding off, it will take Jane
16 min to fill the tank
