How to find the volume of a cylinder

For the ratio, all you need to do is divide the stick into 8 equal parts. Seperate the stick between the third and the fourth section and you're all set.

The wait for that perfect someone may be long and painful, but the payoff lasts even longer, and is the most painless thing in the world.

Llisa's right but if you want to do ratio all you do is add up the two numbers in the ratio. E.g. If you got given 5:4 then you have 9 seperate parts.

So to find what '1' would be, you need to divide the 2m length by 8 (because it is 3:5). Now you've found what '1' is. The first part of the wood would be 3 x whatever the one is and the second part would be 5 x whatever the one is.
When you reach for the stars, you may not quite get them, but you won't come up with a handful of mud either.

Just remember to keep smiling!
