Penjelasan dengan langkah-langkah:

1. a. persen = data/jumlah data × 100%

11/40×100% = 27.5%

17/40×100% = 42.5%

4/40×100% = 10%

5/40×100% = 12.5%

3/40×100% = 7.5%

derajat = persen dikali 3.6

27.5×3.6 = 99°

42.5×3.6 = 153°

10×3.6 = 36°

12.5×3.6 = 45°

7.5×3.6 = 27°

b. bisa dibuat pakai busur ya

2. a. apel = 360 - 54+72+63+81

= 360 - 270

= 90°

b. siswa = derajat/360 × jumlah data

anggur = 72/360×40 = 72÷9 = 8 siswa

nanas = 54/360 × 40 = 54÷9 = 6 siswa

mangga = 63/360 × 40 = 63÷9 = 7 siswa

semangka= 72/360×40 = 72÷8 = 8 siswa

apel= 90/360×40 = 90÷9 = 10 siswa

3. a. 100-20+25+15+10 = 100-70 = 30%

b. banyak murid/100% × jumlah data

36. 15/100×40 = 600÷100 = 6 orang

37. = 30/100 × 40 = 1200÷100 = 12 orang

38. 20/100 × 40 = 800÷100 = 8 orang

39. = 25/100×40 = 1000÷100 = 10 orang

40. 10/100×40 = 400÷100 = 4 orang
