Since the scale factor is 3/4, and the original circle has a radius of 9 inches, we can use the formula:
radius of original circle = (radius of dilated circle) / (scale factor)
radius of original circle = 9 inches / (3/4)
= 9 inches * (4/3)
= 36/3 inches
= 12 inches
So, the radius of the original circle is 12 inches.
radius of original circle = (radius of dilated circle) / (scale factor)
radius of original circle = 9 inches / (3/4)
= 9 inches * (4/3)
= 36/3 inches
= 12 inches
So, the radius of the original circle is 12 inches.
