Question

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?

Answer 1

Let's restate the given:

height of the solution (h) = 2 cm
diameter of the funnel (d) = 3 cm
radius of the funnel (r) = 1.5 cm

The volume of a cone is formulated as V = πr²h/3

To get the correct answer, just substitute the given values.

The final answer is 4.71 cubic centimeters.
