Calculate the angle(a) 1° (degree) (b) 1'(minute of arc or arcmin)and (c) 1"(second of arc or arc second) inradians. Use 360°=2π rad. 1= 60', and1' = 60"

Answer»

We know 360°= 2π rad

=>1°= (π/180) rad = 0.01745 rad

1'= (1/60)°= π/(60 × 180) = 0.00029 rad

1''= (1/3600)°= π/(3600 × 180) = 0.0000048 rad
