What is the linear velocity if angular velocity vector ω→

What is the linear velocity if angular velocity vector ω^{^→} = 3î - 4ĵ - k̂ and position vector r^{^→} = 5î - 6ĵ + 6k̂

1. 6î + 2ĵ - 3k̂
2. -18î - 13ĵ + 2k̂
3. 18î + 13ĵ - 2k̂
4. 6î - 2ĵ + 8k̂

As we know that
v^{^→} = ω^{^→} × r^{^→} = (3î - 4ĵ - k̂) × (5î - 6ĵ + 6k̂)
= -18î - 13ĵ + 2k̂
