Since the scale factor is 3/4, the radius of the original circle can be calculated by taking the dilated radius (9 inches) and dividing it by the scale factor (3/4):
Original radius = 9 inches / (3/4) = 9 inches * (4/3) = 36/3 = 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
