    The radius of the circle is 2.4ft

    Step-by-step explanation:

    circumference of circle = 2πr

    circumference = 15ft

    2πr = 15

    (2*3.14) r = 15

    6.28r = 15

    r = 2.4ft (near. tenth)

    The answer is 2.4 ft.

    Step-by-step explanation:

    C = 2πr

    15 = 2 (3.14) r

    15 = 6.28r

    15:6.28 = 6.28r: 6.28

    2.4 = r
