~Jawab~
Lingkaran
___________________
Pb = 120/360 × 2πr
22 = 1/3 × 2 × 22/7 × r
22 × 3 × 7 = 3 × 2 × 22 × r
462 = 132r
r = 462/132 →3,5 cm
Jawab:
Penjelasan dengan langkah-langkah:
Panjang busur = a/360 × keliling lingkaran
22 = 120/360 × 2 × 22/7 × r
22 = 1/3 × 44r/7
(22 × 3 × 7)/(44) = r
10.5 = r
