Poloměry kružnic čtverce
Čtverci o straně 14 cm je opsána a vepsána kružnice. Urči poloměry obou kružnic.
\( c^{2} = a^{2} + b^{2} \)
\( c^{2} = 196 + 196 \)
\( c = \sqrt{392} \)
\( c ≐ 18,8\ cm \)
\( r = \frac{18,8}{2} \)
\( r = 9,4\ cm \)
\( c^{2} = a^{2} + b^{2} \)
\( c^{2} = 196 + 196 \)
\( c = \sqrt{392} \)
\( c ≐ 19,8\ cm \)
\( r = \frac{19,8}{2} \)
\( r = 9,9\ cm \)
\( c^{2} = a^{2} + b^{2} \)
\( c^{2} = 196 + 196 \)
\( c = \sqrt{392} \)
\( c ≐ 20,8\ cm \)
\( r = \frac{20,8}{2} \)
\( r = 10,4\ cm \)
\( c^{2} = a^{2} + b^{2} \)
\( c^{2} = 196 + 196 \)
\( c = \sqrt{392} \)
\( c ≐ 21,8\ cm \)
\( r = \frac{21,8}{2} \)
\( r = 10,9\ cm \)
