Me i need the correct answer this is so important

First, you need to find the volume of the cone. Using the fomula V = pi r^2 h/3, you get 792000. That's the volume of the cone. The liquid is drained from the container at a rate of 1099 cm^3, so you divide 792000/1099. You get 720.65. That rounds up to 720.7. It would take about 720.7 hours for it to drain all of the liquid.
