~Solution :-
If we take the radius of a circle be R. Then, we can define that,
$ R = x $
Hence,
Arcs will be as $ 4x $. As,
A circle can be divided into four parts according to the radius.
Hence, we know that,
![x * 4](https://img.qammunity.org/2022/formulas/mathematics/college/yi7kjlh96525xtxbhfz5dom1jpdyl7u145.png)
![\mapsto \: 4x](https://img.qammunity.org/2022/formulas/mathematics/college/v0aqyjmkfw7fc92z0qstt90x6ajwhw0hq3.png)
- Hence, according to the radius R, a circle can have 4 arcs.
