How can you tell from the scale factor whether the original figure was enlarged or reduced?

If the scale factor is less then 1, it was reduced.

If the scale factor is more than 1, it was enlarged.

If it is equal to 1, it is the same.

Hope this helps!

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
