Let ABCDEF be a regular hexagon with the centre S and the side of length 3cm. The point G is the midpoint of the segment AB. The vectors u→, v→, w→, z→ are indicated in the hexagon shown in the picture. Find the dot product of: v→⋅w→, v→⋅z→ and v→⋅u→.
v→⋅w→=9, v→⋅z→=0, v→⋅u→=27
v→⋅w→=9, v→⋅z→=0, v→⋅u→=96
v→⋅w→=92, v→⋅z→=0, v→⋅u→=96
v→⋅w→=92, v→⋅z→=1, v→⋅u→=27
