A w h o l e p i e i s 36 0 o A n an g l e e a c h p i e c u t i s 36 0 o : 12 = 3 0 o
It's simple. If there are 360 degrees in a circle, and you're dividing that into 12 pieces, just divide 360 by 12 and get 30 degrees
Each piece of the pie, when cut into twelve equal slices, has an angle of 30 degrees. This is found by dividing the total degrees of a circle, which is 360 degrees, by the number of slices. Therefore, 360 degrees divided by 12 equals 30 degrees for each slice.

Penjelasan dengan langkah-langkah:Diketahui:Jumlah siswa menyanyi (M) = 30Jumlah siswa teater (T) = 34Jumlah siswa melukis (L) = 40Menyanyi dan teater (M ∩ T) = 14 Teater dan melukis (T ∩ L) = 14Menyanyi dan melukis (M ∩ L) = 24Menyanyi, teater, dan melukis (M ∩ T ∩ L) = 10Rumus jumlah total anggota gabungan tiga himpunan: |M ∪ T ∪ L| = |M| + |T| + |L| - |M ∩ T| - |T ∩ L| - |M ∩ L| + |M ∩ T ∩ L|Substitusi nilai:= 30 + 34 + 40 - 14 - 14 - 24 + 10= 104 - 52 + 10= 62Jadi, banyaknya siswa dalam kelompok tersebut adalah 62 orang
