Use Similar Solids and their Scale Factors to find the volume of the smaller Cone.
+1011 I'm Probally not going to be good at this one but with all kindness and respect on this question I belive you need a picture or someting to give this question more descriptive...... That is Probally why no one is answering this...... We dont know what the the smaller cone looks like or the scale factors of the similair solids......... Hope this helps you improve your question Addios!
