    Answer:

    Area = 50.24 units²

    Circumference = 25.12 units

    Step-by-step explanation:

    Circumference = 2\pi r

    =\pi d

    =3.14\times 8

    =25.12

    Area = \pi r^2

    r = 8\div2

    =4

    Area = 3.14\times4^2

    =50.24

    ∴ The circumference of the circle is 25.12 units, and the area of the circle is 50.24 units²

    Hope this helps 🙂
