Question

My circumference is 20 cm what is my diameter and radius?

Answer 1

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.
