# Empty the vessel

A cylindrical vessel with radius $$90 \text{ cm}$$ filled with 3-meter deep water is sitting on a tower, as shown in the diagram. The vessel has a hole on the bottom with a cross-sectional area of $$6.3 \text{ cm}^2$$.

How long (in minutes) will it take before the vessel is completely drained through the hole?

Assume that the gravitational acceleration is $$g = 9.8 \text{ m/s}^2.$$
