Good day
I've been sitting here for about an hour now working on my + task but I can't figure it out.
I need to transform this formula: O=2r²π + 2rπ*h so that r= . I also need to write down a justification for my result. Can you give me some food for thought or write the solution directly? Thanks.

Loading...Why does this calculation result in: (-9) And not (9) ?
Hello, I would have proven i) using induction, but I'm stuck at a certain point. Can anyone tell me if this approach is even correct, and if so, how exactly to do it?
A friend of mine claims that if he bets on numbers in the lottery that have been drawn less frequently in the past, he can slightly increase his probability of winning. He cites some statistical theory (unfortunately, he can't name a source) that supports his theory. Who can prove that he's wrong, even if the…
Does anyone know how these things work? I'm such a loser at chemistry. I just don't understand it.
Be able to calculate at what times a certain elongation / speed / acceleration occurs (I don't understand that at all :/ maybe I'm just too stupid)
How do I solve such a complex absolute value inequality? I can understand why the pole is excluded from the domain of definition. But how do you arrive at the values that satisfy the inequality?
You can’t turn a term into an equation.
You must have 2r2π + 2rπ*h = …. It is probably the
Surface, then you have
O = 2r2π + 2rπ*h
O/(2π) = r2 + r*h
r2 + r*h – O/(2π) = 0
r = -h/2 +- sqrt((h/2)2 + O/(2π))
It’s true the surface… I forgot to mention that. Thank you.
