The scale factor of the first circle with radius 9 in to that of the second circle with diameter 6 in is 3.00

The scale factor of a circle to another is the ratio of their radii

Radius of the first circle = 9 in

Diameter of the second circle = 6 in

Radius = Diameter / 2

Radius of the second circle = 6 / 2

Radius of the second circle = 3 in

Scale factor = (Radius of the first circle) / (Radius of the second circle)

Scale factor = 9/3

Scale factor = 3.00 (2 decimal places)
