The Pythagorean theorem is A^2 + B^2 = C^2. So you will do 9^2 + 12^2 = 225. The square root of 225 is 15, and so is the answer d. hope this helps
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.
The answer is i think 262.08 miles
Answer:
