if i have a beaker with 1 particle in it, and every minute that particle doubles, to 2, to 4, to 8 etc

it starts at 9am, and by 9pm to beaker was full

what time was it half full?

sorry if you already heard this or i've said it, but it's a easier one

Winnie said: How do you know when it's half full when you don't know the capacity of the beaker? :/

Or don't you need to? ARGHHH! Stop distracting me with these funkey problems.

And bennyr, the volume of a cylinder is (pi)r^2h, where (pi) is 3.14..., r is radius and h is height. I just don't know how to express it with only r... =/

I can't seem to find any relationship between r and h, so it's confusing.
