Answer:
Arc EF = 11.30
Step-by-step explanation:
For Circle A
S = r∅
18.08=(8)∅
Where ∅ is the angle subtended by the Arc
So
∅ = 18.08/8
∅ = 2.26 (in radians)
Now
For Circle C
S = (5)(2.26)
S = 11.30
one
its c i belive'
It is the third one because of formula I² + 2I*II + II²
In your case I = 4x and II = 3
