Tentukan berapa derajat dan radian pada pukul a. 00.28 b. 15.48
difaa2
A. 00.28=28menit 1 menit=(1/60)° jadi 28menit = 28x (1/60)° = 0,466° atau (7/15)° 1°=π/180 rad jadi (7/15)°=7/15 x π/180 = 7π/2700 rad b. 15.48 = 948 menit 948menit=948x (1/60)° = 15,8° 15,8°=15,8x π/180=0,087π rad
1 menit=(1/60)° jadi 28menit = 28x (1/60)° = 0,466° atau (7/15)°
1°=π/180 rad jadi
(7/15)°=7/15 x π/180 = 7π/2700 rad
b. 15.48 = 948 menit
948menit=948x (1/60)° = 15,8°
15,8°=15,8x π/180=0,087π rad
