Nt = Lp Balok + Lp ½ Tabung ​

Answer 1

L.Setengah silinder/tabung--LP = πd(r + t) ÷ 2LP = (3,14 × 20 × (5 + 20)) ÷ 2LP = (62,8 × 25) ÷ 2LP = 1.570 ÷ 2LP = 785--L.Balok--LP = 2(pl + pt + lt)LP = 2(20(10) + 20(8) + 10(8))LP = 2(200 + 160 + 80)LP = 2(440)LP = 880 cm²--L.Gabungan--LP = 785 + 880LP = 1.665 cm²[tex] [/tex]

Answer 2

· LP BalokLP = 2 × (P × L + P × T + L × T)LP = 2 × (20 × 10 + 20 × 8 + 10 × 8)LP = 2 × (200 + 160 + 80)LP = 2 × (360 + 80)LP = 2 × 440LP = 880 cm· LP TabungLP = πd× (r + t) : 2LP = (3,14 × 20 + (10 + 20)) : 2LP = (3,14 × 20 + 30) : 2LP = (62,8 × 30) : 2LP = 1.884 : 2LP = 942LP Balok + LP Tabung880 + 942= 1.822 cm²koreksitolong jangan direpot dulu :)
