The curved surface of a cone has an area of \( 4.15\,\mathrm{cm}^2 \). If we flatten it into a plain, we get a sector of a circle with the central angle of \( 126^{\circ} \). Calculate the volume of this cone. Round the result to two decimal places.
\( 0.88\,\mathrm{cm}^3 \)
\( 0.62\,\mathrm{cm}^3 \)
\( 0.15\,\mathrm{cm}^3 \)
\( 311.00\,\mathrm{cm}^3 \)
