Question

many such cones are prepared from the whole metal of cylinder. 6. The radius OP of the sector \( \mathrm { O } - \mathrm { PRQ } \) is 12\( \mathrm { cm } \) and \( \angle \mathrm { POQ } = 120 ^ { \circ } . \mathrm { A } \) cone is formed such that radii OP and OQ coincide. Find the volume of the cone \( ( \pi = 3.14 \) and \( \sqrt { 2 } = 1.41 ) ( H O T S ) \) \( 120 ^ { \circ m } \)
