Bantuin ya gan ini soalnya:volume bangun tersebut adalah ....... gambarnya liat disitu thx.....

V = V 1/2bola + V tabung + V kerucut V = 1/2.4/3 πr³ + πr²t + 1/3.πr²t V = πr² (2/3.r + t + 1/3t) V = 3,14.25 (2/3.5 + 8 + 1/3.12) V = 78,5 (3,33 + 8 + 4) V = 78,5 . 15,33 V = 1203,4
volum krucut v = 1/3 x π x r² x t = 1/3 x 3,14 x 5 x 5 x 12 = 3,14 x 25 x 4 = 314 cm³ volum tabung t = 25 - 5 - 12 = 8 v = π x r² x t = 3,14 x 5 x 5 x 8 = 628 cm³ volum bola v = 1/2 x 4/3 x π x r³ = 2/3 x 3,14 x 5 x 5 x 5 = 2/3 x 392,5 = 785/3 = 261,7
V = 1/2.4/3 πr³ + πr²t + 1/3.πr²t
V = πr² (2/3.r + t + 1/3t)
V = 3,14.25 (2/3.5 + 8 + 1/3.12)
V = 78,5 (3,33 + 8 + 4)
V = 78,5 . 15,33
V = 1203,4
= 5
tinggi krucut
volum krucut
v = 1/3 x π x r² x t
= 1/3 x 3,14 x 5 x 5 x 12
= 3,14 x 25 x 4
= 314 cm³
volum tabung
t = 25 - 5 - 12
= 8
v = π x r² x t
= 3,14 x 5 x 5 x 8
= 628 cm³
volum bola
v = 1/2 x 4/3 x π x r³
= 2/3 x 3,14 x 5 x 5 x 5
= 2/3 x 392,5
= 785/3
= 261,7
jawabnya
= 261,6+314 + 628
= 1203,7 cm³
