Answer:
C. 6.3cm
Step-by-step explanation:
The length of the arc is calculated using the formula;
[tex]l=\frac{Central\:angle}{360\degree} \times 2\pi r[/tex]
The radius of the circle is r=10cm
The central angle is 36 degrees.
[tex]l=\frac{36\degree}{360\degree} \times 2\times3.14\times10[/tex]
We simplify to get;
[tex]l=\frac{1}{10} \times 3.14\times 20[/tex]
[tex]l=3.14\times 2=6.3cm[/tex]
