Answer:

The above expression shows that ratios of the areas of the circles are equal to the square of the ratio of their radii.
Step-by-step explanation:
Radius of first circle
= 9 inches
Area of first circle = 
Area of first circle = 9 × 9 × π = 81 π
Now, since the radius is multiplied by 2/3 for from a new circle.
∴ Radius of the second circle = 
Area of second circle = 
Area of second circle = 6 × 6 × π = 36 π
Now,


∵
= 9 inches and
= 6 inches
The above expression shows that ratios of the areas of the circles are equal to the square of the ratio of their radii. i.e.,
