Circumscribing

Determine the radius of the circumscribed circle to the right triangle with legs 9 cm and 6 cm.

Correct answer:

r =  5.41 cm

Step-by-step explanation:

$$\begin{gathered} a=9 \\ b=6 \\ c=\sqrt{a^2+b^2}=\sqrt{9^2+6^2}=3\sqrt{13}\doteq 10.8167 \\ r=c\mathrm{/}2=10.8167\mathrm{/}2=5.41\text{ cm} \end{gathered}$$
