# Find the degree measures corresponding to the following radian measures (Use π = 22/7).(i) 11/16(ii) – 4(iii) 5π/3(iv) 7π/6

(i) Given: radians

We know that 1 radian = ° = × = × = 39° + 3/8°

Therefore, radian = 39° 22' 30''

We know that 1 radian = °

-4 = - 4 × = -4 × = -229.09°

Now 1º = 60'

0.09º = 0.09 × 60 = 5.4'

Therefore, - 4 radians = - 229º 5.4'

(iii) Given: radian

We know that 1 radian = ° = × = 300° radian = 300°

(iv) Given: radian

We know that 1 radian = ° = × = 210° radian = 210°
