8 radian =………….. Putaran.
Pakai cara
8 phi rad = … derajat
8 x 180
= 1440 derajat
1440 derajat = … putaran
1440 : 360
= 4 putaran
semoga membantu
Penjelasan dengan langkah-langkah:
1 putaran = 2πrad
1 rad = 1 putaran/2π
8π.rad = 8π x 1 putaran/2π
= 4 putaran
360° = 2πrad
180° = πrad
1° = πrad/180
180°/π = 1 rad
8πradian = 8. 180°/π
= (1.440)°
