Answer:

(1)Distance from P to R=circumference of half of the circle

We know that the area of a semicircle is πr+d

but,here we cannot add d to πr.

Because the distance will not be the diameter of circle hence,it is only moving on the curved path

Hence,the distance is πr.

so,putting the values

=2π*3

(2)distance from p to p=circumference of the circle

=2πr

=2*π*3

=6π

(3)displacement from R to P=2r

=2*3

=6

(4)displacement from R to R =0

This can be possible because if final and initial positions are same the the displacement will be zero..

Thank you...
