If you use a scale factor of 1/5 to create a circle with radius 18 cm, what is the radius of the onginal circle you dilated? (1 point) 90 cm 3.6 cm 180 cm 9m, pick one of my answers

Answer 1

The radius of the original circle can be found by multiplying the scale factor by the radius of the dilated circle.

Using a scale factor of 1/5 and a radius of 18 cm, the radius of the original circle would be:

(1/5) * 18 cm = 3.6 cm

Therefore, the correct answer is 3.6 cm.
