    Brady will need 25.12ft of edging

    There are 50.24ft² in bradys garden

    Step-by-step explanation:

    radius = half of diameter

    r = 8ft / 2 = 4ft

    To solve this problem we need to use the circumferenc formula of a circle:

    c = circumference

    r = radius = 4ft

    π = 3.14

    c = 2π * r

    we replace with the known values

    c = 2 * 3.14 * 4ft

    c = 25.12ft

    Brady will need 25.12ft of edging

    To solve the second part of the problem we need to use the area formula of a circle:

    a = area

    r = radius = 4ft

    π = 3.14

    a = π * r²

    we replace with the known values

    a = 3.14 * (4ft) ²

    a = 3.14 * 16ft²

    a = 50.24ft²

    The area of the circle is 50.24ft²
