Express in degrees:

 
a. 4π25 radians

 4π  25 radians

= ( 4π  25 ✕  180    π )°  [We know, 1 radians = 180°/π]

= ( 4π  25 ✕  180    π )°

=  4 ✕ 36    5

= 28.8°




b. 1.3177 radians

    1.3177 radians

= (1.3177 ✕   180    π)°  [We know, 1 radians =   180    π]

= (1.3177 ✕     180   3.1416)°  [We know, π = 3.1416]

= 75.4984° (approx.)




c. 0.9759 radians

    0.9759 radians

= (0.9759 ✕  180    π )°  [We know, 1 radians =   180    π]

= (0.9759 ✕    180 3.1416)°  [We know, π = 3.1416]

= 55.9148° (approx.)
