Find the volume of the cylinder to know how much liquid is in it:


volume of a cylinder = Pi x r^2 x height.


Volume = 3.14 x 60^2 x 210

Volume = 2,373,840 cubic cm


now to find the length of time divide total cubic cm by the drainage rate:


2,373,840 / 1099 = 2,160 hours


Answer: 2,160 hours
