Jawaban:
3a) k.L1 = 1/2.phi.d b)L.l1 =1/2.phi.r2
= 1/2.3,14.3 = 1/2.3,14.1,5
= 47,1 = 35,325
k.L2 = 1/2.phi.d L.l2=1/2.phi.r.r
= 1/2.3,14.4 =1/2.3,14.2'2
= 62,8 =6,28
k.L3 = 1/2.phi.d L.l3=1/2.phi.r.r
= 1/2.3,14.5 =1/2.3,14.2,5'2
= 78,5 = 6,8125
Penjelasan dengan langkah-langkah:
a) jadii keliling bgn yg diarsir :
k.L1 + k.L2 + k.L3
= 47,1 + 62,8 + 78,5
= 188,4
b) jadi luas daerah yg diarsir :
L.l1 + L.l2 + L.L3
= 35,325 + 6,28 + 6,8125
= 48,4175
