Materi : Bangun Ruang Sisi Datar

Volume ½Tabung + Balok

V = plt + ½πr²t

V = 27.19.21 + ½.3,14.9,5.9,5.27

V = 10.773 cm³ + 3.825,6975 cm³

V = 14.598,6975 cm³

Lp ½Tabung + Balok

Lp = ½πdt + 2( pt + lt ) + pl

Lp = ½.3,14.19.27 + 2( 27.21 + 19.21 ) + 27.19

Lp = 805,41 cm² + 46.42 + 513 cm²

Lp = 1.318,41 cm² + 1.932 cm²

Lp = 3.250,41 cm²

Answer 2

V :

= (27(19(21) + (1/2(3,14(9,5²(27)

= (27(399) + (1/2(3,14(90,25(27)

= 10.773 + (1/2(3,14(2.436,75)

= 10.773 + (1/2(7.651,395)

= 10.773 + (7.651,395/2)

= 10.773 + 3.825,6975

= 14.598,6975 CM³

LP :

= (1/2(3,14(19(27) + 2(27(21) + (19(21) + (27(19)

= (1/2(1.610,82) + 2(567 + 399) + 513

= 1.610,82/2 + 2(966) + 513

= 805,41 + 1.932 + 513

= 805,41 + 2.245

= 3.250,41 CM²
