Kak, tolong bantu....
volume gabungan bangun ruang tersebut adalah...

Answer 1

penjelasa dibawah ya

volume kerucut

1/3×π×r²×t

1/3×22/7×7×7×18

22×7=154

154×7=1,078

1,078×18=19,404

1/3×19,404

19,404÷3=6,468 cm³

volume tabung

π×r²×t

22/7×7×7×12

22×7=154

154×7=1,078

1,078×12=12,936 cm³

volume kerucut + volume tabung

6,468 + 12,936

= 19,404 cm³
