Answer:
a. 23.9 ft
Step-by-step explanation:
The circunference of a circle is given by the following formula:
[tex]C = 2\pi r[/tex]
In which r is the radius.
A circle has a diameter of 7.6 feet.
The radius is half the diameter. So
[tex]r = \frac{7.6}{2} = 3.8[/tex]
The circunference is
[tex]C = 2\pi r = 2*3.14*3.8 =23.864[/tex]
So the correct answer is:
a. 23.9 ft
