Because we can transform circle A into circle B by using transformations, we conclude that circle A and B are similar.
<h3>
How to prove that the two circles are similar?</h3>
We know that two figures are similar if one is a transformation of the other. So let's find the transformations that we need to apply to circle A to get circle B.
First, let's move the center. We can see that we need to translate circle A 5 units down and 3 units to the left.
Now, the radius of circle A is 5 units, while the radius of circle B is 2 units, then we have a scale factor k such that:
k*5 units = 2 units
k = 2/5
Then, if we apply the transformations to circle A.
- shift of 5 units down.
- shift of 3 units left.
- dilation of scale factor 2/5.
We get circle B, so circle A and circle B are similar.

<span>A line passes through the point (–7, 5) and has a slope of 1/5.
So this line would be y=1/5x+b
If we substitute x and y into this </span>formula
We can get b=5+7/5=32/5
Then y=1/5x+32/5
If x=0, then y=32/5
So another point on this line is (0,32/5)
yes you are right, density formula is :
density = mass ÷ vol
