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:
(5,4) and (3,4)
Step-by-step explanation:
A line segment has 2 end points which can be denoted as:
and
When this line segment intersects at y.
This means that the coordinate on the y axis is the same at both end points
i.e.
and
becomes
and
x1 and x2 can be any value but the y value must remain unchanged
Using the above analysis, a possible coordinate is:
and
Note that there are as many answers as possible as long as the coordinate pair satisfy is of the form <em> and </em>
<em />
Take for instance, another possible pair is:
and
