Answer 1

The problem statement is ?

Answer 2

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 3

Okay, here is what we are working with. It is a cone, too.

Answer 4

Next up, the forumla for the volume of a right circular cone.

Answer 5

if you added to the attachment i cant see it seems like its not big enough i can only see a portion of t

Answer 6

That is correct. The portion you see is the portion of the original cone in which the stopped-up filter has trapped fluid. Our task is to get the volume of that fluid.

Answer 7

V = 1/3 * π * r^2 * h

V = 1/3 * π *( 1.5)^2 * 2

V = 4.7 cubic cm

Note that the "WolfRam" calculator will do the arithmetic.
