Musya8 [376]

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 = $\frac{C}{\pi }$ </h3>

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.

<h3>The Radius can be Solved using: r = $\frac{c}{2\pi }$ </h3>

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.
