1° = π/180° = 0.005555556π = 0.01745329252 rad
Answer 2) b = 1' = = 0.0002907 radians
Explanation : A minute of arc is π/10800 of radian; which is a measurement unit of angular which is equal to 1/60 of 1° degree.
So substituting the value of 1° as and on solving we get,
0.01745/60 = 0.0002907 radians.
A minute of arc is π/10800 of a radian.
Answer 3) C= 1'' = 4.8481[tex] X 10^{-6} [/tex]
Explanation - When calculating second of arc which is considered to be 1/60 of an arc minute, and 1/3600 of a degree;
So all these are inter-related units which can be calculated if any one value is given;
on solving we get, π/648000 (about 1/206265) of a radian = 4.8481 X [tex] 10^{-6} [/tex]
