Then math is wrong and you're wrong! a=pi(r^2) You are trying to find the area from the radius, period! The formula is valid for ALL the different infinite possible radius that can possibly exist!
That's really not good enough. The math you (and now Motor Daddy -- but he may just be trolling) are butchering starts at about a 7th grade level. You shouldn't even be here trying to have this discussion until you make the effort to become better at math.
While some of the equations were already known, how do you think I was able to create equations without understanding how they work????????? Why is there 4 of each, Russ? Can you answer that? Please Register or Log in to view the hidden image!
Here's some pre-algebra lessons for you guys to start with. Some of it may be review, but I suggest going through all of it because I'm sure there are more gaps than just the one's you've shown us: http://www.coolmath.com/prealgebra/
"Backup" how? What, exactly, do you want me to do? While I'm at it, maybe I should find you guys some remedial English lessons too! Jeez!
In the link you posted it tells how to convert a decimal to a percent. I'm having difficulty converting the decimal 0.999..., can you help?
So the link you posted is too simple, you need different math to convert the decimal 0.999... to a percentage? Can you just save me the time and tell me what the percentage is?
No. I'm hoping that after you complete it, you will be able to answer your question; it is covered in the course. No. If I did that, you wouldn't learn anything. Look, I know you are trying to press your troll by instigating a discussion on your misunderstanding of how repeating decimals work, but it won't work: it isn't needed here and I won't take your troll bait.
But you posted a link you thought would help, and it didn't. Your credibility is fading fast. You won't tell me the percentage, you gave a link that can't do it, and now you send me off somewhere else? Why not just admit that you too don't know the percentage of the decimal 0.999...? Why send me on a wild goose chase if you know? I'll give you a like if you tell me the correct answer. Please?
In order for the link to help you, you actually have to go through the lessons and do the problems. You haven't done that. I'd be more than happy to tutor you, but you should start another thread for that. When trolling, it is best not to act so desperate. It is kinda pathetic - but funny!
Then start with your previous abomination: If r=1, what are you trying to say, that 360=3.14159? That 2.5=3.14159 too? WTF??
