    Answer:

    The diameter of the circle would be: 6.4 cm. rounded or 6.36619772 cm.

    The radius of the circle would be: 3.2 cm. rounded or 3.18309886 cm.

    Step-by-step explanation:

    The diameter can be solved using: D = \frac{C}{\pi }

    So, the first step would be : D = \frac{20}{\pi }

    Then : D = 20 ÷ \pi

    Finally, the answer will be : 6.36619772 cm. or 6.4 cm.

    The Radius can be Solved using: r = \frac{c}{2\pi }

    The first step would be : r = \frac{20}{2\pi }

    Then : 20 ÷ 6.2831853071796 (2\pi)

    Finally, the answer will be : 3.18309886 cm. or 3.2 cm.
