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 = [tex]\frac{C}{\pi }[/tex]

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

Then : D = 20 ÷ [tex]\pi[/tex]

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

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

The first step would be : r = [tex]\frac{20}{2\pi }[/tex]

Then : 20 ÷ 6.2831853071796 (2[tex]\pi[/tex])

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