Right!

like 12sq2+H2=20SQ2

i got 16

You have enough to find volume big cone: (1/3)pi r^2 h
anonymous
  • anonymous
i got 3pih then what next
anonymous
  • anonymous
You know what is H and r for the big cone?
anonymous
  • anonymous
yea 16 and 12
anonymous
  • anonymous
Now use 'similar triangles' to find small cone
anonymous
  • anonymous
what u mean..
anonymous
  • anonymous
Take info from one triangle to find info from another h/16=3/12 solve for h of small cone.
anonymous
  • anonymous
4
anonymous
  • anonymous
Now you have info like you did the big cone
anonymous
  • anonymous
i got 64
anonymous

Good, check your work I was just showing the way. You have a lot of questions; you need this to graduate or what are you working on? :)
anonymous
  • anonymous
i just need help for my homework that all
anonymous
  • anonymous
Keep working, you're pretty sharp.
anonymous
  • anonymous
so i can to find the volume of small cone right
anonymous
  • anonymous
Just follow exactly as you did the big cone. You have to keep track of the methods and techniques.
anonymous
  • anonymous
i just got 4 as volume for small cone
anonymous
  • anonymous
Good, check your work. I don't know.
anonymous
  • anonymous
so now i divide both volume but it have faction as answer
anonymous
  • anonymous
Why are you dividing? I thought you just wanted vol of big cone, vol of small cone.
anonymous
  • anonymous
look up the title it said divide = ?/?
anonymous
  • anonymous
Or do you mean the final answer of each happens to be a fraction? If that is what you mean it is OK it starts with a fraction 1/3; not everything ends in whole numbers.
anonymous
  • anonymous
oh i get and can u help me with the other question?
