Question

In Radian system the angle 40° is equal to ?

​

Answer 1

Answer:

radian measures = pi/180° × degree measures (formula)

Give:

40°

by using the formula,

radian measure = pi/180° × 40°

= 40°pi/180° (divide by 2)

( zero get cancelled on both numerator and denominator)

= 2/9 pi

therefore, answer = 2/9pi
