Ubahlah sudut berikut dalam satuan derajat dan radian a.3/8putaran b.1/3putaran c.7/10putaran d.9/5putaran

jawab

a. 3/8 putaran = 3/8 x 360°= 135 ° = 3/4 π rad

b. 1/3 putaran = 1/3 x 360° = 120° = 2/3 π rad

c. 7/10 putaran = 7/10 x 360°= 252° = 7/5 π rad

d. 9/5 putaran = 9/5 x 360 ° = 648 ° = 18/5 π rad
