Answer:

C. 6.3cm

Explanation:

The length of the arc is calculated using the formula;

$l=(Central\:angle)/(360\degree) * 2\pi r$

The radius of the circle is r=10cm

The central angle is 36 degrees.

$l=(36\degree)/(360\degree) * 2*3.14*10$

We simplify to get;

l=(1)/(10) * 3.14* 20

l=3.14* 2=6.3cm
