Question

The diameters of F and G are 5 and 6 units, respectively. Find each measure.

8. BF

9. AB

I wasn’t at school when we learned this and I don’t know what to do...

Answer 1

Part 8) B.F=0.5 units

Part 9) A.B=2 units

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
