220° = ....rad A. 1 ⅓ π B. 1 ⅔ π C. 1 2/9 π D. 1 4/9 π E. 1 5/3 π tolong pakai caranya yaa

220° = .....rad
(phi/180°)rad × 220°
= 220°/180° phi rad
= 1 40/180 phi rad
= 1 2/9 phi rad (C)

Konversi Sudut.
Kelompok wajib kelas X kurikulum 2013 revisi 2016.

... rad = (π / 180°)(... derajat)
220° = (π / 180°)(220°)
        = 11/9 π rad = 1 2/9 π rad
