Poloměr kružnice z průměru
Znáš průměr kružnice \( k \), jak velký bude poloměr kružnice?
\( \large d = 7,5cm \)
\( \large r = \Large \frac{d}{4}\large = \Large \frac{{7,5}}{4}\large = 1,875cm \)
\( \large r = \Large \frac{d}{2}\large = \Large \frac{{7,5}}{2}\large = 3,75cm \)
\( \large r = \Large \frac{d}{3}\large = \Large \frac{{7,5}}{3}\large = 2,5cm \)
\( \large r = \Large \frac{d}{5}\large = \Large \frac{{7,5}}{5}\large = 1,5cm \)
