Question

What is the central angle of the arc

Answer 1

20°

Explanation:

`\because \: l = ( \theta)/(360 \degree) * c \\ \\ \therefore \: (1)/(3) = ( \theta)/(360 \degree) * 6 \\ \\ \therefore \: \theta = (360 \degree)/(3 * 6) \\ \\ \therefore \: \theta = (360 \degree)/(18) \\ \\ \therefore \: \huge \red{ \boxed{ \theta = 20 \degree}} \\`
