Solution

We know that, 1° = 60' and 1' = 60''

`(1/5)^"c" = (1/5 xx 180/pi)^circ   ...[because 1^"c" = (180/pi)^circ]`

= `(36/pi)^circ`

= `(36/3.14)^circ` 

= (11.46)°

= 11° + (0.46)°

= 11° + (0.46 × 60)'

= 11° + (27.6)'

= 11° + 27' + (0.6)'

= 11° + 27' + (0.6 × 60)''

= 11°27' + 36''

= 11°27'36''.....(approx.)
