The radius of the original circle can be found by dividing the radius of the dilated circle by the scale factor.
So, the radius of the original circle is 18 cm / 15 = 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 90 cm
