Question

convert 47° 30 minute into Radian measure

Answer 1

SOLUTION :

• 47°30'

we know that ,

1 degree = 60' and 1 min = 1/60 degree

So,

= 47 + 30/60 degree

= 47 + 1/2 degree

= 94 + 1/2 degree

= 95/2 degree

180 ° = π radian

1° = π/180 radian

= 95/2 × π/180 radian

= 19/2 × π/36 radian

= 19π/72 radian

So, 47°30' = 19π/72 radian
