e. 1.047 rad

Semoga Membantu

A. 15 = 15 x 2 phi/360
= 15 x 2 x 22/7/360
= 15 x 6,28/360
= 94,2/360
= 0,2616 radian
B. 20 = 20 x 2 phi/360
= 20 x 2 x 22/7/360
= 20 x 6,28/360
= 125,6/360
= 0,3488 radian
C. 36 = 36 x 2 phi/360
= 36 x 2 x 22/7/360
= 36 x 6,28/360
= 226,08/360
= 0,628 radian
D. 45 = 45 x 2 phi/360
= 45 x 2 x 22/7/360
= 45 x 6,28/360
= 282,6/360
= 0,785 radian
E. 60 = 60 x 2 phi/360
= 60 x 2 x 22/7/360
= 60 x 6,28/360
= 376,8/360
= 1,0466 radian
