{{{drawing(300,300,-12,12,-12,12,grid(1),circle(10,0,0.5),blue(circle(0,0,10)),blue(line(0,0,10,0)))}}}
The circle with radius 10 centered at (0,0) represents all the points of rotation. 
At 200 degrees from the x-axis,
{{{x=10cos(200)=-9.397}}}
{{{y=10sin(200)=-3.420}}}
{{{drawing(300,300,-12,12,-12,12,grid(1),circle(-9.397,-3.42,0.5),blue(line(-9.397,-3.42,0,0)),circle(10,0,0.5),blue(circle(0,0,10)),blue(line(0,0,10,0)))}}}
