Please show me the work so i understand
2. Find the reference angle of -11π/3.
5. If θ = –18°, find the exact value of θ in radians.
6.If θ = 3, find the value of θ in degrees correct to the nearest tenth of a degree.
13.The radius of a circle is 6 inches. If the central angle is 5π/3, find the length of the intercepted arc. (Round to the nearest hundredth.)

2.
-11π/3 + 4π = π/3
5.
-18° * π rad/180° = π/10 radians
6.
3rad * 180°/πrad = 540/π = 171.9°
13.
s = rθ = 6*5π/3 = 10π = 31.42 in
