Question

1)Given: AB = 4 AD = 6

Answer 1

1)Given: AB = 4 AD = 6
What is the name of the radius of the larger circle?
the answer part 1) is 
the radius of the larger circle is AD

2)Given: AB = 4 AD = 6
What point is in the interior of both circles?
the answer Part 2) is 
The point A  (the center of the circles)

3) Given: AB = 4 AD = 6
Which points are in the exterior of both circles?
the answer Part 3) is
E and G

4)The circles are _____.
the answer Part 4) is
concentric

5)If AC = 20 and BD = 8, what is the radius of the smaller circle?
we know that
radius smaller circle=AB
and
AB=AC-BD--------> AC=20-12-------> AC=8 units

the answer part 5) is
the radius of the smaller circle is 12 units

6)Given: AB = 4 AD= 6
What is the length of BD?
we know that
AD=AB+BD
solve for BD
BD=AD-AB--------> BD=6-4-----> BD=2 units

the answer Part 6) is
the length of BD is 2

7)Given: AB = 4 AD = 6
What is the name of the radius of the smaller circle?

the answer Part 7) is 
the name of the radius of the smaller circle is AB
