Hexagon 5

The distance of parallel sides of regular hexagons is 97 cm. Calculate the length of the radius of the circle described in this hexagon.

Final Answer:

r =  56 cm

Step-by-step explanation:

$$\begin{gathered} a=97\text{cm} \\ \sin 60°=\frac{a/2}{r} \\ r=\frac{a/2}{\sin 60°}=\frac{a/2}{\sin \pi /3}=\frac{97/2}{\sin \pi /3}=56=56\text{cm} \end{gathered}$$
