The figure shows an equilateral triangle whose side is \( 10\,\mathrm{cm} \) long. The circular sector inside the triangle has the centre at one of the vertices of the triangle, and the arc touches the opposite side. Find the ratio of the circumference of the sector to the perimeter of the triangle. Round the result to one decimal place.
