Answer:
[tex]12\pi \ ft[/tex]
Step-by-step explanation:
we know that
The circumference of a circle is equal to
[tex]C=\pi D[/tex]
where
D is the diameter of the circle
In this problem we have
[tex]D=24\ ft[/tex]
substitute the value
[tex]C=\pi (24)[/tex]
[tex]C=24\pi\ ft [/tex]
In this problem BAC represent a semicircle
therefore
To find the length of BAC, divide the circumference by [tex]2[/tex]
[tex]24\pi/2=12\pi \ ft[/tex]
