Answer:

a. 23.9 ft

Explanation:

The circunference of a circle is given by the following formula:

$C = 2\pi r$

In which r is the radius.

A circle has a diameter of 7.6 feet.

The radius is half the diameter. So

r = (7.6)/(2) = 3.8

The circunference is

$C = 2\pi r = 2*3.14*3.8 =23.864$

So the correct answer is:

a. 23.9 ft
