Question 1132645: Hello!
The problem I have is that I need to "find the volume of a cone slant height of which is nine times the radius and the height of 12√5 units."
Either I am not sure how to write the answer, or I don't understand what is being asked, or I am doing it wrong. I tried 2880π√(5), and 4π√(5)r^2, but neither of those worked.
Thanks for helping!
