The length of the shortest diagonal in a regular polygon is \( 8\,\mathrm{cm} \). The measure of the angle between this diagonal and the side of the polygon is \( 20^{\circ} \). Calculate the radius of a circle circumscribed about this polygon. Round the result to two decimal places.
\( 6.22\,\mathrm{cm} \)
\( 5.22\,\mathrm{cm} \)
\( 4.26\,\mathrm{cm} \)
\( 11.69\,\mathrm{cm} \)
