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:
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 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.
