Distance between A and B is
A. A and B two points on the circumference of the circle with center O and
radius 5.2 cm
B. Angle AOB = 450

• Since A and B are the points on the circumference of circle ,therefore a complete rotation angle along the circumference will be 3360 degree. after on rotation we get back to our initial point on the circumference. so the angle between AOB where O is center is (450-360)=90degree.. that means the Arc AOB forms a Quadrant of the circle the distance AB can be calculated, using pythagoras theorm.. where AB will be hypotenuse. so answer will be AB = 5.2*root(2);

• angle will be=450-360->90,hence distance is (circumference)/4=(2*pi)/4r = 8.8 and displacement is under root of(5.2^2 + 5.2^2)=15.84..

• 15.84 . use d fornula a^2 = b^2 + c^2 -2*b*c*cosAOB.
  a=5.2
  b=5.5
  AOB=45degrees
