Trigonometry

Two wheels are rotating in such a way that the rotation of the smaller wheel causes the larger wheel to rotate. The radius of the smaller wheel is 4.4 centimeters and the radius of the larger wheel is 20.9 centimeters. Through how many degrees wil the larger wheel rotate if the smaller one rotates 89 degrees.
