Convert 40°20' into radian measure
  • 1 answers

Gaurav Seth 6 years, 2 months ago

40 degrees 20 minutes

1 degree = 60 minutes 

1 degree = 60'

⇒ 40 degree 20'

⇒ 40 degree + 20'

⇒ 40° + 20°/60

⇒ 40° + 1°/3 

⇒ (120 + 1)°/3

⇒ 121°/3

We know that Radian measure = π*degree measure/180

⇒ (22*121)/(7*180*3)

⇒ 2662/3780

= 0.704 radians
