Answers

GPT 3.5
To find the radius of the original circle, you need to divide the dilated radius by the scale factor.

Original radius = Dilated radius / Scale factor
Original radius = 9 / (3/4)
Original radius = 9 * (4/3)
Original radius = 12 inches

Therefore, the radius of the original circle is 12 inches.
