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:
<h3>The diameter can be solved using: D =
</h3>
So, the first step would be : D = 
Then : D = 20 ÷ 
Finally, the answer will be : 6.36619772 cm. or 6.4 cm.
<h3>The Radius can be Solved using: r =
</h3>
The first step would be : r = 
Then : 20 ÷ 6.2831853071796 (2)
Finally, the answer will be : 3.18309886 cm. or 3.2 cm.
