Right!

- anonymous

like 12sq2+H2=20SQ2

- anonymous

Right on!

- anonymous

i got 16

- anonymous

You have enough to find volume big cone: (1/3)pi r^2 h

- anonymous

i got 3pih then what next

- anonymous

You know what is H and r for the big cone?

- anonymous

yea 16 and 12

- anonymous

Now use 'similar triangles' to find small cone

- anonymous

what u mean..

- anonymous

Take info from one triangle to find info from another h/16=3/12 solve for h of small cone.

- anonymous

4

- anonymous

Now you have info like you did the big cone

- 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

i just need help for my homework that all

- anonymous

Keep working, you're pretty sharp.

- anonymous

so i can to find the volume of small cone right

- anonymous

Just follow exactly as you did the big cone. You have to keep track of the methods and techniques.

- anonymous

i just got 4 as volume for small cone

- anonymous

Good, check your work. I don't know.

- anonymous

so now i divide both volume but it have faction as answer

- anonymous

Why are you dividing? I thought you just wanted vol of big cone, vol of small cone.

- anonymous

look up the title it said divide = ?/?

- 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

oh i get and can u help me with the other question?
