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.
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
