Jawaban:
(B)
Penjelasan dengan langkah-langkah:
BUSUR LINGKARAN
Jika x = adalah besar <POQ , maka
Panjang busur = x/360° × keliling lingkaran
11 = 45/360 × 22/7 × d ......(d = diameter )
11 = 1/8 × 22/7 × d
d = 11 : 1/8 : 22/7
d = 11 × 8 × 7/22
d = 88 × 7/22
d = 4 × 7
d = 28 cm ← diperoleh diameter
Maka jari jari
= ½ × d
= ½ × 28
= 14 cm (B)
