tolongin dong no 32-33

32) C
33) A

semoga membantu:)

32) sudut busur besar mn = 360 - 80 = 280
panjang busur kecil mn = a/360 × π × d
37,68 = 80/360 × 3,14 × d
37,68 = 2/9 × 3,14 × d
d = 37,68 × 9/2 ÷ 3,14 = 54
panjang busur besar mn = 280/360 × 3,14 × 54
= 7/9 × 3,14 × 54
= 131,88

33) OPQ = OQP = 40
POQ = 180 - OPQ - OQP = 180 - 40 - 40 = 100
PRQ = ½POQ = ½(100) = 50
RQP = RQO + OQP = 15 + 40 = 55
RPQ = 180 - PRQ - RQP = 180 - 50 - 55 = 75
RPO = RPQ - OPQ = 75 - 40 = 35
