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:
300 Square feet 
Step-by-step explanation:
Susan built a rectangular fence around her swimming pool.
Length=15ft
Width(or Breadth)=10ft
Height=6ft
To solve this, picture a cuboid with the top and bottom open, that is the key to finding the Surface Area of the Fence.
Surface Area of a Cuboid= 2(LW+LH+WH)
However since the top and bottom are open, the Surface Area becomes
Surface Area of the fence= 2(LW+WH)
                                        =2((15X6)+(10X6)
                                        =2(90+60)=2 X 150 =300
Susan uses 300 Square feet to build her fence.
