One of the questions that came up on the exam the other day [#permalink]

One of the questions that came up on the exam the other day was a geometry/rate question. Unfortunately I don't recall the exact numbers, but was wondering if someone could explain how to approach such a question. The question said: there is a right circular cylinder (did not provide any dimensions) and said that it would take ~10 hours to fill the cylinder with water and that the height of the cylinder increased by ~0.5 meters per hour. What is the radius of the cylinder? Any ideas on how to solve such a problem?
