Question

Find length of minor arc in a circle include correct unit

Answer 1

`(22\pi )/(3) \: m`

Explanation:

`central \: \angle ( \theta)\: for \: major \: arc \\ = 360 \degree - 30 \degree = 330 \degree \\ radius \: (r) = 4 \: m \\ length \: of \: major \: \overset{\frown} {ACB} \: \\ = ( \theta)/(360 \degree)* 2\pi \: r \\ \\ = ( 330 \degree)/(360 \degree)* 2 \pi * 4 \\ \\ = ( 11 )/(12)* 2 \pi * 4 \\ \\ = (22\pi )/(3) \: m`
