how to convert radian to degrees ??

Answer :

Convert degree to radian

Since 1 revolution in a unit circle satisfies

 360° = 2π radians  

Dividing by 2 both sides

 180° = π radians

Dividing by 180 both sides

 1° = 𝜋/180 radians

• To Convert 30°  degree to radian

Since 1° = 𝜋/180 radians

Hence 30° = 30*𝜋/180 radians = 𝜋/6

• To Convert 45°  degree to radian

Since 1° = 𝜋/180 radians

Hence 45° = 45*𝜋/180 radians = 𝜋/4

• To Convert 60°  degree to radian

Since 1° = 𝜋/180 radians

Hence 60° = 60*𝜋/180 radians = 𝜋/3

• To Convert 90°  degree to radian

Since 1° = 𝜋/180 radians

Hence 90° = 90*𝜋/180 radians = 𝜋/2 radian
