tolong dijawab yaaaa
Jawaban:
diket
Diameter = D = 28 cm
jari jari = r = 1/2 D = 1/2 x 28 = 14 cm
Tinggi = t = 35 cm
ditanya
Volume tabung diluar kerucut
jawab
Menentukan volume kerucut
V kerucut = 1/3 x luas alas x tinggi
V kerucut = 1/3 (π x r²) x t
V kerucut = 1/3 (22/7 x 14²) x 35
V kerucut = 1/3 (22/7 x 196) x 35
V kerucut = 1/3 (22 x 28) x 35
V kerucut = 1/3 x 21.560
V kerucut = 7186,67 cm³
Menentukan volume tabung
V tabung = π x r² x t
V tabung = 22/7 x 14² x 35
V tabung = 22/7 x 196 x 35
V tabung = 22 x 28 x 35
V tabung = 21.560 cm³
Menentukan volume tabung diluar kerucut
V tabung - V kerucut
21.560 - 7186,67
= 14.373,33 cm³

Jawaban:
volume kerucut
- V= 1/3 x π x r x r x t
- =1/3×22/7×14×14×35
- =7,186.67 cm3
volume tabung:
- V = π × r × r × t
- =22/7×14×14×35
- =21,560 cm3
volume kerucut --- volume tabung;
7,186.67 -- 21,560 =14,373.33 cm3
