Jawaban:
Panjang busur:
Bangun Datar Lingkaran
Diketahui:
Jari - jari (r) OB = 14 cm → d = 2r = 2(14 cm) = 28 cm
Sudut pusat lingkaran (AOB) = 90⁰
Panjang busur AB;
P.AB = <AOB/360⁰ x π x diameter
P.AB = 90⁰/360⁰ x 22/7 x 28 cm
P.AB = 1/4 x 22 x 4 cm
P.AB = 1/4 x 88 cm
P.AB = 22 cm
Jadi, panjang busur AB adalah 22 cm (A).
