✔ 最佳答案
食 : 84
百分比 = (84/312) x 100% = 26.923%
Angle of sector = (84/312) x 360 = 96.923°
功課 : 20
百分比 = (20/312) x 100% = 6.410%
Angle of sector = (20/312) x 360 = 23.077°
溫習 : 42
百分比 = (42/312) x 100% = 13.462%
Angle of sector = (42/312) x 360 = 48.462°
閱讀 : 54
百分比 = (54/312) x 100% = 17.308%
Angle of sector = (54/312) x 360 = 62.308°
畫畫 : 3
百分比 = (3/312) x 100% = 0.962%
Angle of sector = (3/312) x 360 = 3.462°
上網 : 24
百分比 = (24/312) x 100% = 7.692%
Angle of sector = (24/312) x 360 = 27.692°
聽音樂 : 40
百分比 = (40/312) x 100% = 12.821%
Angle of sector = (40/312) x 360 = 46.154°
種植 : 45
百分比 = (45/312) x 100% = 14.423%
Angle of sector = (45/312) x 360 = 51.923°
