1) A completely full underground oil reservoir is the shape of a perfectly round disk, similar to an ordinary
coin but much, much larger. The disk has radius 400[m] and thickness of 9[m]. If oil is pumped out of
the reservoir at a constant rate of 333 liters/second until the reservoir is empty, approximately how long
will the pumps have to run to drain the reservoir of its oil? Hint: 1 liter = 1,000[cm³]. The volume of a
disk is Area * thickness.
