In the adjoining figure, calculate:
(i) the length of minor are ACB
(ii) area of shaded sector

Explanation

Here, `theta = 150^(@), r = 14 cm`
(i) Length of minor arc `= (pi r theta)/(180^(@))`
`= (22)/(7) xx 14 xx 150^(@) xx (1)/(360^(@))`
`= 36.67 cm`
(ii) Area of shaded sector `= (pi r^(2) theta)/(360^(@)) = (22)/(7) xx (14)^(2) xx 150^(@) xx (1)/(360^(@)) = 256.67 cm^(2)`
