The correct answer is 1.2 cm.

To find the radius of the original circle, you need to divide the radius of the dilated circle by the scale factor.

Radius of the original circle = Radius of the dilated circle / Scale factor
Radius of the original circle = 18 cm / 15
Radius of the original circle = 1.2 cm
