Given:
The scale factor between two circles is
.
To find:
The ratio of their areas.
Solution:
We know that, all circles are similar.
The ratio of the areas of similar figures is equal to the ratio of squares of their corresponding sides or equal to the square of ratio of their corresponding sides.
The scale factor is the ratio of the corresponding sides.
Ratio of areas of circles = Square of scale factor between two circles



Therefore, the correct option is D.
Answer: 110 horses
Step-by-step explanation:
Given
An average adult horse needs two fifth bale of hay
The farm has 44 bales of hay
Suppose n horses can be fed by the available bales of hay
So, we can write

Surface area o fthe ball = 4 * 3.14 * radius^2
if diameter = 1.680 then radius = 1/2 * 1.680 = 0.84
so surface area = 4 * 3.14 * 0.84^2 = 8.862
