Jazz = 14 siswa

Keroncong = 5 siswa

Rock = 10 siswa

Jumlah seluruh siswa = 6+21+14+5+10

= 56 siswa

Ditanya:

Besar sudut dangdut = ... °

Presentase dangdut = ...%

Besar sudut pop = ... °

Presentase pop = ...%

Besar sudut jazz = ... °

Presentase jazz = ...%

Besar sudut keroncong = ... °

Presentase keroncong = ...%

Besar sudut rock = ... °

Presentase rock = ...%

Penyelesaian:

• Dangdut

Besar Sudut = 6/56 × 360° = 38,57°

Presentase = 6/56 × 100% = 10,71%

• Pop

Besar Sudut = 21/56 × 360° = 135°

Presentase = 21/56 × 100% = 37,5%

• Jazz

Besar Sudut = 14/56 × 360° = 90°

Presentase = 14/56 × 100% = 25%

• Keroncong

Besar Sudut = 5/56 × 360° = 32,14°

Presentase = 5/56 × 100% = 8,92%

• Rock

Besar Sudut = 10/56 × 360° = 64,28°

Presentase = 10/56 × 100% = 17,85%

Semoga membantu:)
