You use scale factor of 3/4 to create a dilated circle with a radius of 9 inches. What is the radius of the original circle?(1 point) inches
The radius of the original circle can be calculated by dividing the radius of the dilated circle by the scale factor.
Original radius = Dilated radius / Scale factor
Original radius = 9 inches / (3/4)
Original radius = 9 inches * (4/3)
Original radius = 12 inches
Therefore, the radius of the original circle is 12 inches.
