1)given: ab = 4 ad = 6 what is the name of the radius of the larger circle? a ab ad 2)given: ab = 4 ad = 6 what point is in the interior of both circles? h a b 3) given: ab = 4 ad = 6 which points are in the exterior of both circles? e and g h and f h and g 4)the circles are concentric congruent collinear sequential 5)if ac = 20 and bd = 8, what is the radius of the smaller circle? 8 10 12 6)given: ab = 4 ad= 6 what is the length of bd? 2 4 6 7)given: ab = 4 ad = 6 what is the name of the radius of the smaller circle? a ab ad

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

Ithink if im not mistaking b is -3 but im not a 100% sude
