makasih banyak, bantuan nya

Juring POQ = 60/360 Lingkaran.
Juring POQ = 1/6 Lingkaran.

K. Lingkaran
= 22 × 6.
= 132cm.

Juring ROS = 150/360 Lingkaran.
Juring ROS = 5/12 Lingkaran.

Panjang busur RS
= 132 × 5/12.
= 55cm.

Jawaban : B.

langsung aja yy

juring QOP = 60/360 = 1/6
juring ROS = 150/360 = 5/12

K = 22 × 6 = 132

maka
panjang busur RS
132 × 5/12 = 55

jawabannya B

semoga berguna +_+
