Sebuah piza dipotong menjadi 6 bagia Sudut setiap potong piza sebes 60°. Panjang busur PQ sebesar 22 or Hitunglah: a. jari-jari piza, b. luas tiap potong piza.

A. Attached with answer.
B. According to image Students which are in neither = 154 -72 -35 + 20 = 67
C = Students who play jazz but not marching band = Students in Jazz band - Student who can do both = 35 - 20 = 15

In total, there are 67 students who are in neither the marching band nor the jazz band. Additionally, 15 students are in the jazz band but not in the marching band. The Venn Diagram shows 52 students in the marching band only, 15 in the jazz band only, and 20 in both bands.

Jawaban:a. Jari-jari piza Sudut pusat satu potong pizza = 60° = (60/360) * 2πr = (1/6) * 2πr Panjang busur PQ = (1/6) * 2πr = 22 cm 2πr/6 = 22 cm 2πr = 132 cm r = 132 cm / 2π Menggunakan nilai π ≈ 22/7, kita peroleh: r ≈ 132 cm / (2 * 22/7) r ≈ 132 cm * 7/44 r ≈ 21 cm Jadi, jari-jari pizza adalah 21 cm. b. Luas tiap potong pizza Luas seluruh pizza = πr² = π * (21 cm)² ≈ 1386 cm² Luas tiap potong pizza = Luas seluruh pizza / 6 = 1386 cm² / 6 ≈ 231 cm² Jadi, luas tiap potong pizza adalah sekitar 231 cm².
