hello?

Answer 5

Hey sorry, I was helping a few others. Yes, that's right. Now, can you tell me the volume of the cone in this question?

Answer 6

v=3.14*58^2*150/3

Answer 7

Yep, exactly. Which comes out as 528148cm^3. We have water filling this at a rate of 1750cm^3 per minute, so how long would it take to fill?
