The radius of the original circle can be found by dividing the radius of the dilated circle by the scale factor.
Radius of original circle = Radius of dilated circle / Scale factor
Radius of original circle = 18 cm / 15
Radius of original circle = 1.2 cm
If you use a scale factor of 15 to create a circle with radius 18 cm, what is the radius of the original circle you dilated?(1 point) Responses 3.6 cm 3.6 cm 180 cm 180 cm 9 m 9 m 90 cm
