Answer:
The radius of circle B is 6 times greater than the radius of circle A
The area of circle B is 36 times greater than the area of circle A
Step-by-step explanation:
we have
<em>Circle A</em>
The radius of circle A is
-----> the radius is half the diameter
<em>Circle B</em>
Compare the radius of both circles
The radius of circle B is six times greater than the radius of circle A
Remember that , if two figures are similar, then the ratio of its areas is equal to the scale factor squared
All circles are similar
In this problem the scale factor is 6
so
therefore
The area of circle B is 36 times greater than the area of circle A
Answer:
The length of other base is <u>30 in</u>.
Step-by-step explanation:
Given:
A trapezoid has an area of 184 in^2. The height is 8 in and the length of one base is 16 in.
Now, to get the length of other base.
Let the length of other base be
Area of trapezoid = 184 in².
Height of trapezoid () = 8 in.
Length of one base (a) = 16 in.
Now, to get the length of other base of trapezoid we solve an equation:
<em /><em />
<em>Subtracting both sides by 64 we get:</em>
<em /><em />
<em>Dividing both sides by 4 we get:</em>
Therefore, the length of other base is 30 in.
