A funnel has a filter that was being used to remove impurities from a solution, but it became clogged and stopped draining. The remaining solution is represented by the colored region. The top of the solution is 2 cm from the bottom of the funnel and at a point where the diameter of the funnel is 3 cm. Assuming the funnel is cone-shaped, how many cubic centimeters of the solution should remain in the funnel?
