    Step-by-step explanation:

    Circumference of a circle = 2πr

    2πr = 6.28

    r = 6.28/2π

    r = 3.142/π

    Area of a circle = πr^2

    slot in the value of r

    Area of the circle = π (3.142/π) ^2

    " = π (9.87 / π^2)

    " = 9.87/π

    π = 3.14

    Area of a circle = 9.867 / (3.14)

    " = 3.14 square units
