Answer:
Part 8) B.F=0.5 units
Part 9) A.B=2 units
Step-by-step explanation:
we have
The diameter of circle F is 5 units
so
The radius of circle F is r.f=5/2=2.5 units
The diameter of circle G is 6 units
so
The radius of circle G is r.g=6/2=3 units
Part 8) Find B.F
we know that
B.F=G.B-F.G
we have
G.B=rg=3 units
FG=rf=2.5 units
substitute the values
B.F=3-2.5=0.5 units
Part 9) Find A.B
we know that
A.B=A.F-B.F
we have
A.F=r.f=2.5 units
B.F=0.5 units
substitute the values
A.B=2.5-0.5=2 units
For this case we have the following expressions:
