Question

If you use a scale factor of 1/5 to create a circle with radius 18 cm, what is the radius of the original circle you dilated?(1 point)

Answer 1

Answer: I hope this helps!!!!! :)

Explanation:

The radius of the initial circle you dilated would be equal to 18 cm divided by 1/5 if you used a scale factor of 1/5 to produce a circle with a radius of 18 cm. This is the same as multiplying 18 cm by 1/5's reciprocal, or 5/1. Hence, the original circle's radius would indeed be 18 cm × 5/1 = 90 cm

Answer 2

If you use a scale factor of 1/5 to create a circle with radius 18 cm, then the radius of the original circle you dilated would be 18 cm divided by 1/5. This is equivalent to multiplying 18 cm by the reciprocal of 1/5, which is 5/1. Therefore, the radius of the original circle would be:

18 cm × 5/1 = 90 cm

So the original circle had a radius of 90 cm before it was dilated with a scale factor of 1/5.
