    The circumference of the circle is determined by using the equation, C = 2πr. From this, the value of r may be solved by rearranging the equation to, r = C/2π. Substituting the given values,

    r = 15 ft / (2 x 3.14)

    The value of r is 2.3885 ft. Thus, the answer to the question is 2.4 ft.
