The angles converted to radian are as follows:
30° = 0.523599 rad
45° = 0.785398 rad
90° = 1.5708 rad
180° = 3.14159 rad
Degree to radian conversion:
Therefore,
a.
1° = 0.0174533 rad
30° = ?
cross multiply
angles in radian = 30 × 0.0174533 = 0.523599 rad
b.
1° = 0.0174533 rad
45° = ?
angles in radian = 45 × 0.0174533 = 0.785398 rad
c.
1° = 0.0174533 rad
90° = ?
angles in radian = 90 × 0.0174533 = 1.5708 rad
d.
1° = 0.0174533 rad
180° = ?
angles in radian = 180 × 0.0174533 = 3.14159 rad
