Poloměr kružnice z průměru
Znáš průměr kružnice \( k \), jak velký bude poloměr kružnice?
\( \large d = 2cm \)
\( \large r = \Large \frac{d}{3}\large = \Large \frac{2}{3}\large = 0.67cm \)
\( \large r = \Large \frac{d}{2}\large = \Large \frac{2}{2}\large = 1cm \)
\( \large r = \Large \frac{d}{5}\large = \Large \frac{2}{5}\large = 0.4cm \)
\( \large r = \Large \frac{d}{4}\large = \Large \frac{2}{4}\large = 0.5cm \)
