Asked by CharlotteSo you need to use the formula of a cone which is V=pi * r^2 * h/3 you know the volume and the ratio so r/h=3/4, r=3h/4. So from the first formula 768pi=pi*(3h/4)^2*h/3 768=9h^2/16*h/3 768=9h^3/16*3 768=9h^3/48 768*48=9h^3 36864=9h^3 4096=h^3 h=16 If you don’t understand something just let me know. Good luck!
