Question

find the radian measure of 40°20'
​

Answer 1

Answer:

We know that, 1 degree = 60 min or 1° = 60′

40° 20′ = 40° + 20′

= 40° + (20°/60°)

= 40° + (1/3)°

= (120° + 1°)/3°

= 121°/3

Also,

Radian measure = (π/180°) × Degree measure

= (π/180°) × (121°/3)

= (121/540)π

Therefore, 40° 20′ is equal to (121/540)π radians.
