wyznacz ze wzoru wskazana wielkosc. P=wzor na pole kola. wyznacz r, V=pi R kwadrat * H wyznacz R P=(a+b)h wyznacz b 2

[latex]\\ P= Pi r^2 |: Pi \\ r^2=frac{P}{Pi} \\ r= sqrt{frac{P}{Pi}}\\\ V= Pi R^2 cdot H |:H \\ Pi R^2=frac{V}{H} |: Pi \\ R^2=frac{V}{H cdot Pi} \\ R=sqrt{frac{V}{HPi} }\\\ P=frac{(a+b)h}{2}| cdot 2 \\ (a+b)h=2P|:h \\ a+b=frac{2P}{h} |-a \\ b=frac{2P}{h}-a[/latex]

P=πr²|:π r²=P/π r=√(P/π)    V=πR²*H |:πH R²=V/πH R=√V / √πH   P=1/2*(a+b)*h |*2 2P=(a+b)*h |:h 2P/h=a+b |-a b=(2P/h)-a
