# Hexagon 5

The distance of parallel sides of regular hexagonal is 61 cm. Calculate the length of the radius of the circle described to this hexagon.

Result

r =  35.22 cm

#### Solution:

$\sin 60^\circ = \dfrac{ a/2}{ r } = \dfrac{ 61/2}{ r } \ \\ r = \dfrac{ 61/2}{ \sin 60^\circ } = 35.22 \ \text{ cm }$
