Answer:
B) 3.44 feet
The Radius of the circle 'r' = 3.439 ≅3.44 feet
Step-by-step explanation
Step(i):-
Given data the length of arc = 3.6 feet long
l = 3.6 feet
Given central angle 'θ' = [tex]\frac{3}{9} \pi[/tex]
Step(ii):-
The arc length 'l' of a circle of radius 'r' with central angle 'θ' radians is given by
Arc length l = r θ
3.6 = r ([tex]\frac{3}{9} \pi[/tex])
put π = 3.14
now simplification, we get
[tex]r = \frac{3.6 X9}{3\pi }[/tex]
[tex]r = \frac{3.6 X9}{3X3.14 } = \frac{32.4}{9.42} = 3.439[/tex]
Conclusion:-
The Radius of the circle 'r' = 3.439 ≅3.44 feet
