Question

panjang busur BC =

tolong yang bisa bantu​

Answer 1

K lingkaran = 2πr = 2 × 22/7 × 14 = 88 cm

Panjang busur/K lingkaran = sudut pusat/360°

Busur BC/88 = 60°/360°

Busur BC/88 = 1/6

Busur BC = 88/6

Busur BC = 14,6666...

Busur BC ≈ 14,67 cm

Jadi, panjang busur BC adalah 14,67 cm.

Answer 2

Verified answer

Penjelasan dengan langkah-langkah:

B / K = x / 360°

B / 2πr = 60 / 360

B / 2x22/7x14 = 60 / 360

B/88 = 60 / 360

B/88 =1/6

6B=88

B=14,666
