Step-by-step explanation:
Radius of the Circle = 50cm
Let the point be at A
It turns forward 210 degrees to B.
Therefore, the central angle subtended by the arc AB = 210 degrees
The movement of the point from A to B will be the length of the arc AB.

I represent the imaginary part like a+bi where a is the real part
but in the other words i = sqrt(-1)
