dasar :
* 1 putaran = 2π radian = 2.(3,14) radian = 6,28 radian
* 1 putaran = 360 °.
a) 1/9 Putaran
* Derajat = 1/9 x 360 = 40°
* Radian = 1/9 x 6,28 = 0,697 atau 0,7 Radian.
b) 3/8 Putaran
* Derajat = 3/8 x 360 = 135°
* Radian = 3/8 x 6,28 = 2,355 atau 2,36 Radian.
c) 1/5 Putaran
* Derajat = 1/5 x 360 = 72°
* Radian = 1/5 x 6,28 = 1,256 atau 1,26 Radian.
d) 9/8 Putaran
* Derajat = 9/8 x 360 = 648°
* Radian = 9/8 x 6,28 = 7,065 atau 7,07 Radian.
e) 3/4 Putaran
* Derajat = 3/4 x 360 = 270°
* Radian = 3/4 x 6,28 = 4,71 Radian.
f) 7/6 Putaran
* Derajat = 7/6 x 360 = 420°
* Radian = 7/6 x 6,28 = 7,326 atau 7,33 Radian.
